Aliasing on high gain sounds is undetectable for me, if the oversampling is set at 8x. 4x is usually acceptable.
It's nice that it can be used as a full rig plugin, or as individual plugin effects. I'm not totally in love with the amp model, (it's not bad, just a bit lacking in character, which I suppose is expected for a "pedal platform" amp.) so it's nice to be able to just drag an instance and put it in front of whatever I want. The stars of the show are the pedals, though, and they are good. My favorite is the Hard Drive. The distortion is super smooth. and sounds great in front of anything.
My complaints are that the full suite is $143, which is more than Amplitube 5 Max is usually on sale for. (I think you can currently get a bundle of everything Amplitube makes, except for add-ons for $99!) That's more than a hardware JHS Hard Drive would run you, which this plugin is making me want.
If you're looking for a pretty simple but high quality plugin that's similar in structure to something from Neural DSP, I'd highly recommend this, especially if you're a "pedal platform" kind of player. I frankly wish it was a bit more robust, and as usual, they do the thing where you have a screen full of blank cabinet grill and have to click on tabs to change full size graphic representations of each pedal effect.
