DaVinci Resolve.
Totally free for most use.
Stable.
Tons of tutorials.
Oh, did I mention it's not fucking Adobe?
Yeah it's not Adobe.

sorry Im not giving up photoshop and premiere pro.
Premiere pro is unstable garbage compared to DaVinci.
There are ways to make Gimp look like Photoshop but I can agree somewhat. Photoshop is harder to give up.
Affinity Suite is very comparable. They don't have the AI stuff Adobe has been incorporating. But once you get over the learning curve it is great.
I second Da Vinci. I switched from Adobe when I grew tired of their sneaky ways and subscription model. Very comparable and in ways easier to use. If you pay for it(one time payment!), Fusion is on par with After Effects.
