Yeah like I said I've owned two of them myself but when my wife stopped wanting to shoot I got rid of all of them and I'm back to my original set up. I love the 5D classic but my issue is finding a good one that isn't going to break. Honestly the reliability is mainly what I worry about. Since they are around 10 years old A lot of them are starting to go out and it's pretty expensive to replace as opposed to just getting a brand-new crop sensor Mirrorless or something like that

The point was that it doesn't matter what camera you take. "Best" is such a relative term.
Right now, for me, the "best" camera for what I like doing when I'm out with my family would be maybe the new Hasselblad X1D-50c. Smaller system (I mean seriously look how small it is now!) medium format, all the wonderful range that size sensor provides, etc. $9k plus lenses is steep and I can't afford it. And a D810 probably compares at the dynamic range and recovery measurements, they're probably similar enough to not warrant it. But, I like the look of medium format field of view and depth of field effects, so I lean towards the more interesting, to me, looking camera system. But I actually dislike the idea of 50MP, as I prefer smaller files for faster work flow. I wouldn't want a terabyte of photos to process after a family outing. This is why I enjoy a smaller resolution, like 8~12MP. Granted, it's so new, I've not used one, but feature wise, it grabs me instantly and it will have modern quality, so that's a no brainer. But, a digital, slim size medium format camera that syncs at all it's shutter speeds with flash and has that depth of field look that medium format has? I drool at the idea. Unaffordable.
I'm not saying to go get a 5Dc, my point was that what matters is you simply have a camera, and use it. Just use it well. It's more important to capture great compositions, great expressions, your memories, rather than fuss about image quality, cost ratio analysis, etc. At least to me. I could be wrong. It's not a perspective for everyone.
Personally I just like the look of the files that come out of a 1Dc, 1D II, 1Ds II and 5Dc. It changes with the III and later cameras, in the Canon line, where they just don't have that "look" that those previous series had. That newest stuff is better, technically. But I care about the subjective side of it more than the technical side, when simply capturing and enjoying memories of the family.
You want something smaller than a 6D, you want "best" (without defining what best is for you), and you're talking about something being durable, and noting the cost of replacing a $300 camera as being expensive compared to buying a new modern crop, without really making much difference in the look of the images that come from the two devices.
Sounds to me like ultimately a Fuji with 1 or 2 lenses, tops (a fast wide prime, and a single decent wide to mid range zoom) would be a great system for the things you've described a bit.
Or heck, take a look at a Sony RX100 III if you want small with a ton of quality that is modern.
Or, if you really want to take a look at something very interesting, there's the weird, small, really strangely beautiful files that come from a Sigma DP2.
Very best,
