Bah... have owned or played nearly everything in modelers, profilers, etc. Give me a tube amp (or two) ANY day of the week over any of them. I still keep the Tonelab around, but the Kemper is gone, the 11R is gone, the Fractal never was (tried one, don't own one), etc.
I will say this... if you're a tweaker then I can see all of the excitement over these things. I've always been a player. When I get a new amp or pedal, I dial-up the tones that I'm looking for right away and I play and really experience the gear and immerse myself in it. I can't do that if I'm constantly fiddling with the parameters. But I'm a pretty basic guy when it comes to tones and FX. Give me a good Fender or Marshall tone, flavor to taste, give me some basic, transparent chorus, delay, reverb, wah, etc FX... and I've got all I need. I'm not trying to reproduce tones from The Edge or Dave Gilmour to the tee. Though with Gilmour, it's MUCH more about feel and tone than it is about racks of FX (his own touring rig notwithstanding).
Anyways... the clips of Pete Thorn that GoneShootin posted aren't a fair fight anyways. That guy could (and does) make ALL gear sound amazing. I've purchased more than a few items based solely on his clips (including my Plexitone, which I still own and love).
One more thing pertaining to my personal tone journey... I've been through a lot of boutique channel switchers and multi-fx pedals these past few years as well. My Bogner XTC and TC G-System were probably my favorites of these. But I've come to the conclusion that the more wires, circuits and diodes that are in my tone chain, the mushier it comes out on the other end. I want pristine clarity, dynamics, and note-definition. By putting a million miles of circuitry in-between my guitar and my speakers... I'm making that pristine tone harder to maintain.
