Agree with the complications with paid services. The nice thing about Figma is that you get a fully functional tool in the free tier, without trial limitations. Their limitations are built more around length of version history and that kind of thing.
Re: their vector editing, definitely check out what they call Vector Networks. I linked to an article above, but this video is great too
Specifically, there are aspects like easily punching holes in overlapping shapes and simplifying multiple point splines into more evenly curved paths that I wouldn’t want to live without.
But yes, there are also other UI features that make it pretty unique.
We use multiplayer (or the ability to have multiple simultaneous editors) to share designs across our team in real time without any kind of .ai or w/e file sharing needed.
Some times one person will be doing design prep, and another will be actually doing the GF processing. Both can have the same figma file open, and the second can just do the svg export + GF upload while the first can be running ahead wrapping up subsequent print files to be cut.
