I have both and end up using both, probably out of boredom or in the interest in trying to learn each one well. I can get good sounds from each. If I had to pick my favorite I'd say Amp3 as it has a more realistic tube amp sound and character. I've experimented with cabinet sims but for my workflow I usually don't bother. I used to be more into reamping things later with one of my 5 real amps but that's not the case so much anymore as all this stuff sounds really nice! I do think it helps to have a nice signal chain going in. I use the MOTU zbox I to an API 3124 or Reddi.
I don't have Guitar Rig 5 yet, but I've been using ReValver III.V and Guitar Rig 4, plus I've tried Overloud TH1 and LePou plug ins as well. They're all good and have their own strengths and weaknesses.
I recently bought the full version of Amplitube 3 while IK had their 3 for 1 sale on and have to say I'm really impressed. It's awesome. The custom shop is a great idea and I've bought a few of the new pieces there recently too. The Soldano amp, Engl (Anger) amp, Power Grid and T-Rex Møller pedals are fantastic and I use all of them a lot. There are also some amazing presets posted by other users who obviously know how to get the best out of the software.
After using all of the other programs I mentioned I'd have to say Amplitube 3 wins!
+1 on the IR loader feature for Amplitube, although there's nothing wrong with the supplied cabinets. The flexibility would be good though.
I like the amps in amplitube better but the effects in guitar rig and the cab/mic stuff from two notes. My favorite sim setup right now is the slo amp in amplitube going into a parallel effects chain in guitar rig and then into pi-free. My next purchase will most likely be the full torpedo pi product, it's the best cab/mic product I've heard yet. The guitar rig stuff is more flexible but I think the amplitube stuff sounds better - except the effects.
I've been in love with Amplitube since ever.
Amplitube 3.7 got stucked in my mind...
BUT, I've tried 2 guitars into my audio interface and then routed to my DAW and lot of samples and some MIDI at the same time. NO WAY for Amplitube, saddly.
Also tried Amplitube into Reaper loops/markers and etc., it had lost to Guitar Rig. Amplitube seems to clip or bug my RAM with Reaper loops.
I really love Amplitube tones, amps, UI and the ease of use, but the RAM/CPU killer thing is bugging me a lot. I like to have 3 or 3+ channels of guitars into the same project or live setup and some MIDI channels routed to the Amplitube tracks. Unfortunately, it's killing my RAM and CPU, something that Guitar Rig (or the new stuff I'm about to try) isn't.
