A couple years back I was tinkering with a spacemacs setup and I loved Magit!
Over the years I opted to substitute most tools with simpler, UI-based ones (like LogSeq for org-mode) but I never found a good substitution for Magit.
Having a whole spacemacs setup just for one tool is a bit overkill though, so I just use basic git and accept having to deal with interactive rebases manually.
I have a Emacs + Spacemacs setup only for Magit. The base Spacemacs config works well, so I never had the need to tinker with it. Nowadays I don't care much about the rest of Emacs. It stays out of the way, and I keep happily using Magit.
