PSP7 vs PSP8

I'm sorry if its inappropriate to post here, but I couldn't think of anywhere else to ask and from experience, you guys are dead helpful, so here goes.

I've used a few graphic programs in the past, mainly PS7 and PSP8. Recently my computer got reformatted and my PS7 and PSP8 were deleted. I'm more used to PSP8 but I checked around on which programs people prefer and I've found that many think PSP7 is better than PSP8. I'm torn between the 2 versions and I was wondering if I could get your opinion on which you prefer and, most importantly, why. Thank you for your help.
