The difference that C6 makes is that you can flip a little switch on a Folder Track and everything in that Folder is grouped - that makes a lot of sense and keeps things nice and tidy. It certainly helps when you're dealing with multi drum mic's, or DI + amped guitars tracks and the like.
So far, other than the ludicrous decision (if such it is, and not an oversight) to set all channel types to the same colour, there's nothing to dislike so far. In fact I'm even considering breaking my rule and running live with C6 before the second fix release! Nah!
