The D40 was a good camera to learn on, but I switched to a Canon 60D for all-around PJ use. High school football and LAX, some hoops and baseball. I loved having affordable fast glass options. Added a 6D when I phased out of PJ, and I loved it.
I sold the 60D, added the a6000, and I really found myself taking it y. At the time I was mostly using the 6D with the 50A, so I figured I could lighten my bag by replacing it with the a7r/FE55.
I added A-mount after I decided I wanted to shoot out to 200 2.8 natively--picked up a used a77 for cheap and I really enjoyed it. Upgraded to a77ii for about $200 more and it is a fantastic body for my needs.
Nikon really got my attention with the D500 and D810, but I'm pretty happy with the shooting experience and quality of my files with Sony.
The battery stuff is overblown IMO. Getting 500-600 shots is no big deal on e-mount, and I've gotten nearly 900 out of the a77ii. Nobody will confuse that with what Nikon or Canon flagship bodies get, and if you need 3,000 shots out of a battery that is obviously the way to go.
One thing regarding e-mount that is surprising is Sony's omission of a second card slot for wedding and event shooters. Now that the GM lenses are out (and even sometimes available), it seems like they have to make that happen.
the battery life issue can be compared to smart phones.... when they hit the market, people with dumb phones had days of battery life, however people slowly warmed up to phones that could do a crapload of stuff on top of just calling...... now they're used as GPS, text messages, email, social media, and gaming devices. If you're a casual shooter, the battery will get you by 99/100 days. If you shoot a lot like I do, then a single battery will get you by 98/100 days 
it just changes your behavior and you adapt. Turns out, I carry my camera around more than my DSLR setup, which I was carrying around A LOT. If you like it you'll find a way to use it, no different than the moment you start shooting a DSLR over a point and shoot, or the time that you switched from JPEG to RAW. If the benefits are worth it, you adapt, if not, you simply go back to your old method.
the battery issue exists, sure. You're going from a camera that could do 1000+ frames to one that does 400-700... You may find out that adapting is hardly an issue, or find out it's too tough to overcome. You really wont know till you try. Many of my older uncles and aunts still use an older dumb phone. It does the trick for them.
