they're dope looking first of all which attract most people. they are very easy to put on/take off and also adjust, they do make different flex's so you could pick out a boot similar to your nordica if you wanted. They make a slimmer fitting boot (classic) and then the newer shell the influence..? i think, which is for wider feet. so really they make a boot for just about everyone and they work great!
I have seen some big mountain dudes ripping around on them, but if I spent any more time charging lines, i would want a bit burlier boot like a dalbello krypton. I ride the influence shell, and for me it is too soft, not just the tongue but the forefoot and sloe of the boot itself. When i put on a boot i want to feel like i'm locked in tight, and they feel a bit sloppy. The regular fulltilt shell doesn't have these problems and are really solid boots. But when it comes down to it, get a boot that fits well. You can have the nicest boots in the world and they can ruin your day if they fit badly.
