Not GP, but as a LR user, I actually did try alternatives and wasn't impressed. They're usually just as expensive, except if you expect to use the software for multiple years without upgrading, which, to GP's point, would have had you miss out on quite substantial improvements.

I'm a hobbyist, and the new "AI" masking has saved me a lot of time during my edits. Is it as good as a professional path tool wielder? Probably not, but that's not relevant to my use case.
