Bought Revalver 4 - quickly got annoyed with the "oh, you need to buy *this*, too" nickle-and-diming and gave up on it.
Bought BIAS FX Pro for $199, and at the time it included everything there was to have. Since then, they've added some expansion packs for additional money, but I don't have presets that expect those packs to exist, so not a problem. (I suppose it'd be an issue if I used their Sound Cloud thingy, but I don't.)
Would have liked to see them make me a "hey, as an FX Pro user, here, have all 3 expansions for, say $79 or so", rather than $50 each. If only for the 'completionist' collector thrill of "having it all". I don't need them, and $150 for all 3 is irritatingly close to the price of the (far more useful to me) product itself, so...
Briefly looked at Amplitube when I read about their Fender 2 pack modeling lesser-known Fender amps of the '50s and '60s. Downloaded the demo and played with it a bit, but could see the "insert more money here" game that soured me on Revalver. And wasn't so enamored of the modeling or the UI that I wanted to spend $499 for the "gimme all the crap and stop screwing with me" bundle.
Anyhow, I'd say BIAS FX Pro is the least annoying of the guitar packages I've seen. For what that's worth.
