I did a bit of a shoot-out at home recently to find the one I liked best, here's what I found...
For testing I ran my Ibanez RG3120 Prestige into the Instrument input of my
NI Audio Kontrol and hosted the VSTs in Ableton 7. I started with Guitar Rig combos again to use its high background noise in high-gain modes as a kind of base level. As usual the Plexi combo dialled up sounds like crap when playing lightly or resting between notes.
Amplitube 2 was up first, tested some high-gain modes. The master noise-gate is a great touch, and overall the tones are really usable, way more so than GR. In a straight-up Amplitube2 vs Guitar Rig 3 theres no contest, Amplitube is the clear and instant winner.
Amplitube Jimi up next, mostly centred around crunch and other old-school effects, sounds nice but overall doesn't sound too different from Amplitube2s rock presets.
Amplitube Metal is easily one of my faves. Straight up just playing with presets it went from insane gain to really sparkling heavy-metal-intro style cleans. The stomp boxes are great, so are the rack effects.
Flying Haggis has a really visually unique gui, looks awesome and has a decent range of tones and stompboxes but doesnt seem to specialise in any particular sound which can be a good thing depending on your needs. A good classic amp model.
Nomad Factory Rock Amp Legends is great. The first thing I did was select a high-gain mode and I got.. silence - until I bashed out a power chord, these guys have sorted out their background noise more than any of the other amps so far. Really nice rock tones, doesn't have changing amp pictures like the Amplitube ones though.
Studio Devil is another hissy one until I cranked up the noise gate, its a simple affair but its distortion was a little fizzy for my liking and the noise gate was introducing odd noise when it kicked in and out.
Steinberg Warp had a sleek gui and decently low background noise but like Studio Devil I had trouble getting a meaty, high-gain chug sound without either introducing too much fizx or background noise.
Waves GTR is another nice looking vst, great stompboxes, cool amps. Some very warm clean and rock sounds, but a little buzzy in the high-gain modes and trying to dial it out by backing off treble, gain etc just dulls the tone a little. Pretty good overall.

I'll play around with them all some more but for me Amplitube Metal is the winner so far. Nomad is a close second in sound but overall it fell slightly short because of its lack of versatility and mostly static ui, compared to Metal which comes with all these shiny fun noisy toys which go from crystal clean to insane gain and everything in-between:

In fact its so good I'm considering getting the matching stomp controller, shame it costs so much though:

Overall I'd say if you want virtual amp modelling with clean cleans, tonnes of high-gain and fx I'd rank them in this order:
