One beer that I use secondary on often is an IPA with a ton of hop matter in the wort. Sometimes, I'll rack into secondary before dry hopping to leave a bunch of the crap at the bottom. Or sometimes I'll just throw the dry hops in the primary. In either case, after dry hopping, I will almost always rack to another carboy and then cold crash at 40F or so for a week before kegging or bottling.
An IPA we brewed using this process won a silver medal at a competition less than a month ago, so it doesn't suck. That being said, there are lots of ways to getting to good beer, secondary or not.
