Drysuit boots: attached or separate

[jasondbaker]

I'm almost at the finishline deciding on my new drysuit configuration. The last decision I need to make is whether to go with standard attached boots or socks w/ rock boots on my suit. My initial thought was to go with the socks. But I have been surprised at how many experienced divers prefer attached boots.

Are attached boots warmer? Are rock boots a pain to put on/take off? Is there a significant advantage to using either type in our local waters?
