I was also frustrated with the poor git support by blueprints. I ended up just writing long commit messages so that I could read about what I (thought) I had changed
At least this would allow diff, merge, and code review with standard tools.
I also tried Git LFS and it is a hot mess.
Even ignoring the distributed aspect of git, the things I loved as a solo developer was immediate branching, a sane way of merging, and things being fast because there was no server to talk to (coming from SVN and CVS).
Now that I think more about it, I think some of the game studios I'm familiar with were using Git for the engine and artists were using Perforce for their assets.
