BLOWN AWAY by TH2. I own Guitar Rig(3, 4, 5), Revalver, Line 6 Pod Farm(2), POD XT Live, POD X3 Live, plus I use the LE version of Eleven as well as Ampire. I have to say TH2 is hands down the best for me. I liked it so much, I went and bought the X2 upgrade version for $99. First off, for me I need software that has a true standalone mode for those late night jams and moments when most of my song concepts come to me from playing around. This has that. The tones are exceptionally well done. The interface is simple, and very easy to manipulate. What sold me was the sound, especially the spatial sounds from some of the ambience patches. The metal tones are wicked - with less high end "fizz" that I normally have to shape out of the Pod stuff. The low ends are detailed, and punchy. You pretty much have all the stomps you need as well.
Slight knock on the GUI- especially on my MacBook Pro, but I can live with it for now. A STEAL @ $99.00
