Corel's version vs. JASC PSP9?

[Spinny]

I started using PSP at version 4, to do the graphics for my thesis. Since then I've upgraded twice, to 7 and then to 9--the last version before Corel bought them out. I know that at the very least Corel hobbled it by deleting Animation Shop, which is still my favorite go-to app for making animated .gifs.

So, if I were to consider upgrading again, what else has Corel done to it, good and bad? My attitude is they tried to take it out of competition with Corel Draw so probably did it more harm than good (like they did when they completely killed WebDraw, the best SVG editor out there at the time), hence my stopping at 9. Still, I saw there's an active forum about it here and you guys would be more honest than I'd expect from Corel's own forums, so I'm asking here. I'm liking Xtreme but I have years invested in PSP so I hate just to abandon it.

Thanks in advance!
