Me too, I don't think I can function without JetBrain products as an engineer. It is ridiculously powerful. PyCharm + Database tab + Debugger + Little calculator icon for impromptu interpreter + long tail of features that totally make it amazing. I don't use built in Git but I heard that's great too. The database feature has stuff like copy results of a query as INSERT statements. Mind blown.
The built-in git is honestly quite intuitive while still being pretty powerful. I haven't tried other GUI-like git integrations but I was a fan of IntelliJ's.
That said I was talking to a friend about how great it was and he was like "yeah all these things you describe seem like they were lifted from magit" so I suppose once again the answer is "magit is still the best".
Maybe if I ever have the motivation to actually set up an editor I'll try Spacemacs again but I get frustrated when things don't just work and end up going down the configuration rabbit hole anyway.
