IMO as long as animation isn't tied to After Effects like Lottie is, you can't go wrong. The fact that the most popular open vector animation format is tied to an expensive, proprietary piece of software that isn't even primarily a vector art package makes me very sad…
Not to mention After Effects is an extremely poorly performing and highly bloated piece of software tied to mountains of spyware… It’s almost impressive how bad the software is by modern standards.
I find After Effects to be one of the most impressive pieces of creative software ever made. An entire industry had been built around it. That said, there is plenty to improve upon.
