I would say teleosts are better at being teleosts and coelacanths are better at being coelacanths. Apples and oranges.

I'm guessing that you wish to imply by your statement that "more species = more successful = more progress". How about this then; the family Hominidae has only four living species (and three of those are not doing so well these days), while there are over 1600 species of mosquitoes (Culicidae) in the world today. Did skeeters therefore undergo more "progress" than naked apes?

Rather than attemptying to define what "progress" might mean in an evolutionary context, it may be better just to discard the term altogether. The word misleads more than educates.
