I noticed quite the hit in the low light performance dept when I stepped down from canon FF to Sony APS-c. I may be wrong here and have no desire to debate the rules of light and physics with anyone (I say this cause last time I mentioned this on a forum I got plastered with a bunch of technical mumbo jumbo). But it's been my experience that when using a copy sensor you will need a slower SS for any given ISO in order to get good exposure when compared to it's FF counterpart. In the end this has forced me to use higher ISO's in order to get decent SS's in low light conditions. I find this a little crippling from time to time. On top of that, I feel that images on the whole are cleaner at the higher ISO's on FF than APS-c. Having said this, I'm willing (for now) to sacrifice a little low light performance as I absolutely LOVE the small size of my APS-c kit and less expensive lenses. What I will admit (and this is something Eddie mentioned they other day in a post) is that I miss the shallow Dof with FF sensor cameras. I keep tossing around the idea of picking up an 85mm prime for that little extra subject separation (as well as a little extra reach) from time to time. What I'd really like to see (and this is totally a pipe dream that will likely never happen) is a small/lightweight 70-200 F2 APS-c zoom. But I digress.....
On another note....IMO just because someone is no longer super serious about their photography or they consider themselves only a hobbyist is not a strong argument for switching to APS-c and tolerating a lesser quality overall experience. Switching to save a few bucks or for the smaller/lighter kit is totally reasonable. But, just because someone uses their gear primarily to document family stuff doesn't mean they only need or deserve an APS-c system. So don't sell short your Friday night family snapshots at Chillis!
Lastly,
Thanks for your insight in this. I appreciate you taking the time. I've run the whole circle when it comes to gear, starting from my first mirrorless, the NEX-6 to m4/3, to FF, to even trying a GFX for about a week to see what all the buzz is about. It could be just my emotions coming from the NEX-6 since it was my first real camera that I took serious and that I put around 40,000 shots through of my first months with my wife to the birth of my oldest daughter, to our first real family trips. I took about half of those pictures with just the NEX-6 and the 24mm 1.8. I look back at those photos with the fondest of memories, but then again it could've been taken with a potato and I probably would've been fine with it. I see memories and not shallow DoF or ISO noise, I just think that I'm starting to get to a point where there are diminishing returns when it comes to gear. Sure it would be nice to save a few bucks here and there, but we all know that between buying gear, selling gear, trying new gear out that it's a end loss. I'm starting to get more and more into video lately, not film making by any means, just documenting more family events/moment with video and the old 18-105 that I used with my 6500 was a great lens for the power zoom, the parafocal nature, and just the overall range, so that'd be one of the lenses that I pickup. I'm pricing out a 18-105, a 56 1.4, and the pancake 20mm f/2.8, then I could hold off on the Ricoh GR possibly and go with a 20mm f/2.8 as my ultra small setup, the 56 for portraits of the kids, and the 18-105 for the rest of walking around.

Possibly....

But we all have different needs, desires, spare finances, time, etc etc
I just think you should sit on it for a while. Don't rush into a decision & regret it.
You say you don't do paid or serious photography, you're just more of a 'snapshot guy' - So do you really need the super AF of the A6400? Or is it the size/weight/portability? I would imagine the A7iii & Tamron f/2.8 zoom is quite a capable kit?
It's a mix between size/weight/portability, but also wanting the super AF. Don't get me wrong, the a7III is a great kit and I love the 28-75 2.8 more than the GM I used to have as well. With my older daughter turning 6 and her wanting to get more into outdoor activities, being able to carry a smaller 6400, capture a few snapshots, but also have acceptable quality is a middle ground that I'm trying to find.

This hobby can get out of hand financially if you're not careful. My GAS was probably among the worst here at one point.... I downsized my kit out of financial necessity last year and the interesting thing is that it took nothing away from my actual photography. Things are all good now financially and photography business is taking off but I'm still trying to keep a level head about things. I'm really focusing on what is absolutely necessary for me and not getting caught up in marketing hype because thats really what was happening
At any rate, I've been processing two weddings over the past couple of weeks....my second shoots Fuji and I had an a6500 for one of the weddings. I'd say that nowadays APS-C is a lot closer to FF in real world use. The sensitivity of these sensors are so good that even aps-c is really clean until you start hitting extremes, and even then, the noise is very uniform so it's not as aesthetically bothersome as back in the day when banding would ruin photos.
You're looking at basically 1 stop in signal noise difference between FF and apsc...its really not that much in the grand scheme of things it's pretty easy to make up one stop of ISO through composition (flash, SS, f-stop).
Definitely, it can get crazy. Going through a situation where we were down to 1 income, even if it lasted only 10 days, was an eye opener for my wife. I had no doubt that it would not last at all, but for her she decided to go into survival mode. I don't think this potential move is motivated much by finances, at the end of the day the difference between selling an a7III and Tamron and buying the 6400, the 18-105, the 56, and maybe the 20mm will be a net difference of only a couple hundred bucks. But as I consider getting the Ricoh GR a week or so ago, I start to realize that I use my gear less and less now, which I know is not gear related at all. There are times that I'll go 10-15 days between picking up my camera. Having crummy weather outside certainly doesn't help to motivate me to go outside.
I appreciate all the insight guys, it's nice to have people I can talk to and tell me that I'm crazy or that I'm thinking rationally. I am going to pickup the a6400 this weekend though and run it through it's paces. What I do have going for me is that I know what a capable camera the a7III and the 28-75 is and that at worst I can always fall back on it if desired.
