I kind of felt the same thing, althought when I compared the XTlive with the TOnelab SE at guitar center, only the SE had me coming back for more. I didnt find so many presets though and this I wonder it could be because the folks go there and tweak the heck out of the floor model. I kind of wished I could have done some kind of factory reset, if possible to hear everything the SE could deliver, and may the same on the XT live, althought the XT live, I did see a bunch more presets to mess with.
But I could definitely feel the Jump and AIR on the SE for sure. IT was clearly there, while playing through a Marshall amp on clean, and also through headphones. While the XT live reminded me of just a regular floor pedal, while some patches did make it sound good, there was definitely the AIR factor, or Ambience feel sort of speak to it, that I definitely heard on the SE.
I personally own the Genesis 3, and have been looking for a Control X for ages, with no luck, I really do like the sound and quality of the G3, but I wanted something to carry around and practice with, but that I could also record with. I dont know, but I think im going to stay with the G3 as well for now, at least till I find an awsome deal on a used SE. I also really like the Harmonizer effect of the G3, which none of the current effect boards offer. But anyways, the SE did have a true tube sound. I could definitely hear the coloration.
