I used SpaceVim for a month or two, and it was good, but I switched to LunarVim and it's amazing! Been using it for ~6 months.

As you say, updates are a bit rough. I've given up on updating,and periodically I just reinstall it from scratch (a fairly painless process, they did amazing at making it easy to install). I figure this is comes with the territory of a rapidly evolving package.

The Treesitter and LSP features give me real-time code intelligence that I had been missing, and has made porting python2->python3, especially with type annotations, so much easier!
