Personally, I never took to VII well. It just never appealed very much to me. I didn't like Cloud, I didn't particularly like the other cast. I don't know... The parts just add up in a form which I just dislike.
The story just isn't for me. I prefer the fantasy settings of say, VI or the mixture that is X. I just dislike Cloud's attitude.
Maybe I'll give it another shot in a few years.
What didn't you like about FF7? Sorry if this post seems a little dumb I just couldn't find any reasoning in your post other than FF6 has a better setting (which I've never played) and FF10 has a better mix (no idea what that means).
