Alternatives to After Effects/Fusion?

Hi! I work as a videographer, and in the past year I've started editing in Resolve, which work wonders for what I do and is very stable. Fusion is ok for my needs but a little too complicated, or better: time consuming.

Is there some tool that's a little easier both on the learning curve and on the implementation? Or I just have to be stuck with After/Fusion? Most of the time I just need some animated UI or text animation.

I've heard about LottieLab and Rive, but I'm unsure on the options.

Thanks for the help
