I had been using kdenlive for quite a while. I am learning Olive to get accustomed to nonlinear editing before I take on Resolve. I am really liking Olive, since it works fantastically for the kind of stuff I tend to do.
Honestly, because Resolve has been a pain to get working on the distro I use and I can't be bothered to trouble shoot a behemoth like that for a hobby that I'd like to enjoy immediately. One day I'll get it working after plugging away at it.
