Fully class less.

Unless you are interested in analyzing the small part of the game between out of book and middle-game. On these, Loop does way better than Zappa and Rybka (But once you are on early middle game (and beyond), Rybka and Zappa destroy Loop - Another thing to note is that if you are out of book on a middle game position, then Loop is useless, but if you are on an unusual opening [very early out of book] Loop shines).
