i have the seaquest diva lx and find it very comfortable. it's a hybrid, but i've never had any of the mention problems like having the tendency to lie on my face on surface, etc.
i love the weight integration system. it won't come of accidentally but is still easy to dump. also there are weight pockets at the back near the tank.
other than that i like it coz it's closed in from, i tried a seaquest qd + but felt my belly was looking out to much and felt unprotected. it's not so bulky and the air is distributed to the sides and back and not all at the sides.
what i don't like are the pockets. i also have an old scubapro with velcro pockets which i really like. most of the new jackets use zips which are rather hard to access while wearing the jacket.
another cool thing is there is a knife specially for the seaquest jackets that you can attach to your bc.
but like mentioned above, what suits one might not suit the other. try out various bcs at your lds. if you like one or two go home and do an internet search, that way you can find out a lot of the pros and cons of that jacket. it would also be good to make a list beforehand of what you would like and what you definitely don't want. for me it things i wanted were: integrated weights, comfortable, black color, easy to attach a knife since i hate the knife on my leg, big pockets.
sometimes you won't find exactly what you want, for me it might not have been black or the pockets aren't quite to my liking. happens sometimes. nothing's perfect, but should be close to!
