I 've said this before, but why not again...I've had it since November or December. I'm no fan boy and I'll be honest. IMO The Princeton, the Twin and the Deluxe are addictively good. Dirt boxes, reverbs and delays are great. The only dirty amps I care for (Plexi, 800 and Jubilee) leave things to be desired. Pitch shifting not good mainly due to latency.
That said, my only contemporary modeler experience is the Boss GX-100, which I find awful. Based on what I read (and hear on YT), the QC and Fractal are better than the TMP but I don't really know. The Helix sounds kind of thin to me. On YT though.
I guess I haven't been of much help...
