I personally don't like modern high gain amps. I get the feeling that most of the guys that bash modelers aren't into that type of amp either. I do use modelers but I don't have expectations of them sounding authentic. They just don't cut it in that respect.........probably never will. I use them to sketch out song ideas and for making noise.
Warrengtype, you don't know what any of us like sound wise unless you ask. Just because you found someone's half baked song using a modeler doesn't mean you know what type of sound they really want. Some guitar sounds that I like include early ZZ Top, early AC/DC, Thin Lizzy, some Dino Jr., The Black Crowes, and SRV. None of which I can mimic in a modeler. Some modelers are acceptable at best for this type of stuff but none do it well and Amplitube does it exceptionally bad. Here's a page with some clips of an amp that I think sounds good:

Now, when you can pull those types of sounds out of a modeler, I'll shut my mouth.
Until then, see ya around.
