I like an unattached neoprene hood with my DUI shell suit. I use a 6mm hood
for cold stuff and a polartech hood for warmer (cave) stuff.
So I guess it comes down to a basic principle. Fit and Comfort, what you are
most happy with for your diving. Keep it simple, ie seperate hood for ease of
replacement or change for conditions.
Just another 2 pennies.

Subject: RE: Dry Suit Hoods

I currently dive with an O.S. Systems dry suit with out an attached
hood. The coldest I have been so far is 42 Deg. F. When I was shopping
for my dry suit I tried on several with attached hoods as well as
several with out. What helped me make my decision is that If I am going
to be diving in water between 47 and 60 deg. F, I will not need the
extreme thermal protection that an attached will offer. I also found it
harder to pull on. On the forth dive of the day on a boat in the Channel
Islands here off California coast where the air temp can be 100 deg F, I
would be getting in and out of the too much for my comfort. I also
intend on replacing my own neck and wrist seals (after a demonstration
from my local SCUBA shop tech) to save overall cost. I can always
purchase a new hood if I rip it on a wreck without having to replace or
patch the my suit. Also I tend to dive in water at or around 55 to 60
deg. F and having the dry suit is just pure heaven, however, a hood is
not always necessary when the air temp is in the high n 90's
