6 is mine, and I like 8 more than 7 (and for the record I do consider 7 one of the best RPGs ever made) but objectively speaking I think 6 and 7 were both so revolutionary for their respective platforms that people will tend to prefer whichever of the two they played first.
That's why I don't get involved in retarded 6 vs 7 online arguments. I think 7 is a perfectly valid choice. I just prefer 6.
