I love the Fizik stuff because it is very thin, little padding, durable, and long lasting. If you like thin tapes (and probably only if you like thin tapes), you'll love Fizik stuff.

Everyone I know who loves thicker tapes like Cinelli Cork hate it. I've also heard good things about Specialized tape.

Lizard Skins seems to get the most love, but I haven't tried it. If I ever can justify that much for tape, or find it on sale somewhere, I will definitely buy it.
