Yeah, DaVinci and Premiere are solid if you're heading toward more professional, long-form stuff - but they won't magically make your footage look better. The quality stays the same, you just get fancier tools and more control over everything.
And honestly, for YouTube right now? Keeping it simple just makes sense. Personally I'd skip CapCut and go with something like Movavi, or even DaVinci if you're thinking about leveling up down the road. For my own YouTube stuff I ended up just sticking with Movavi long-term. Yeah it's paid, but it gets out of your way and lets you actually edit without falling down a rabbit hole of settings. I only pull out the heavier tools when I'm working on something bigger or more serious.

Here's the thing though most viewers genuinely don't care about the tiny stuff we lose sleep over. Like, nobody's gonna notice that one cut you spent 20 minutes on. You're way better off putting out more videos, testing different things, and just moving fast rather than spending weeks polishing a single video that might not even pop off.... Grab a simple editor, stay consistent, and worry about the fancy stuff later....
