What do you think about Dotnetnuke 6.0.X

Hostmyservices.com has recently started hosting dotnetnuke 6.0 websites coming from 5.4 I still haven't seen the great benefits of switching to dotnetnuke 6.0 please let me know you experiences, so far i find the interface GUI has a more futuristic look which I like a lot since dotnetnuke always has an old bulky look to it.
