I haven't heard them when Syd was still with them, but my favorite album is Wish You Were Here. Sadly I haven't heard all of their music, but I also really like Animals, Meddle, and The Wall. Momentary lapse is pretty cool too, and so is Dark Side, though I think it's kinda overhyped as it's not their best IMO. Though I consider myself a big Floyd fan, I don't really know enough about their history to vote on my favorite member. I guess you could look at my favorite albums and judge from that, though it's probably a mix. But I'd say my top two are WYWH and Animals, though I also really like the song Echoes from Meddle and The Wall movie.
