Which WordPerfect was the perfect WordPerfect?

I am having an exchange with a lady who insists that WordPerfect 6.1 published by Novell is superior to more recent versions published by Corel. She has not explained why she holds this view — perhaps it is just a matter of familiarity. But as we are having a friendly “argument” about this, I would appreciate opinions from any peers who have had experience with both the Novell version and the more recent (many) Corel versions.
