Lazygit is an alternative which worked great so far for me
It's great that all these options are becoming available and bringing ideas into the mix.
At least for the stability issues, does this match your experience?
I see others have mentioned tig here as well, I'd be curious to hear if they also find it somewhat slow and unstable. Gitui's linux benchmark lists it as being almost 11 times faster than tig.
There's a sample config in the repo on how to manage large repos
The design works very very well for me.
