I love the way FireBird sounds, but not having an OS X version forced me to consider other options instead of buying. I ended up getting a version of reFX Vanguard and I think I'll pickup Gladiator also - that should mostly cover the same bases (basses... haha, ahem... heh)
I've always thought of Firebird as a baby brother to Gladiator. Firebird was my first T2 purchase and after that I couldn't help buying Glad 2 and Warmverb as well. I have to say though, even though
I own Gladiator as well, I still turn to Firebird whenever I need edgy sounds in a hurry (Gladiator is of course a bit more involved when programming patches, so ye
). It's just SO beefy. I think a lot of people write if off due to how simple it looks [compared to Glad 2] without considering that this thing can really WHALE! Aww well, their loss
