3D printing Blender users: Would you advise to leave Blender 2.9 behind?

As the title suggests I'm still using blender 2.9 for creating/modifying geometry for printing.

I saw a lot of things improved or got changed for Blender 3, but only for people that want to render or animate stuff.

Is there someone willing to share their experience when it comes to only modifying geometry, is it worth learning where all the things that got rearranged are in the newer versions?
