Yeah, 75% of people say that, love it for about 2 weeks, and then wish they didn't sell their tube amp for one. Fractal is king. Kemper is a close second. Nothing else on the market even comes close to either of them. Orange Amps just release a butt-ugly digital amp that sounds just as butt-ugly, but hey, they're trying to catch up to the crowd. They aren't the only ones. There are a couple, and I think Milkman amps even came out with a digital amp box recently. As much as I like the Fractal stuff, and as cool as some of the new innovations are, tube amps always win.
You might think they're good for practice and recording, but they're really only good for recording IMO. If you practice on one for a week or two then you will have to regain your feel of tube amps again. It's not the same. They don't feel right, so I don't think they're good for practice. You can use them live as many people do, but they don't have the punch or the midrange to cut through like a tube amp can. Even a 25w EL84 amp has more punch and cut than a modeling amp. I have heard a couple of bands using a tube power amp with a Fractal or Kemper, and that's as close as you're going to get. For recording though, I cannot disagree that they sound so good... especially since the guys who usually demo them are skilled players.
