Diving Dry is somewhat of an oxymoron. You are not dry, even if your suit does not leak a drop you will have a significant amount of condensation / sweat. This is why under garments are so important, the good ones keep you warm even when damp. So if you expect the comfort of PJ's, your expectations are too high. However, not being an ice cube is a good thing.
I was a diehard wet suit diver for a long time and I do admit now that I have a dry suit is makes a lot of dives more comfortable. But is is also bulky, increases by air use a bit and had more maintenance issues, not to mention an obscene price tag. For this reason I continue to dive wet when weather permits (at least 5 months of the year), its simply easier to just enjoy the dives.
