I had time this morning and I wanted to see if what I read was right. So I profiled some old and some new presets of Amplitube 3 to try and see by myself. They are no perfect, but for a first try, I'm happy to say that these are better than I expected. I used Ownhammer IR's only, so I bypassed the part of Amplitube that I did not like.
Tell me if it's better or worst than you thought after a try.
