I have a Bare 7 mm wetsuit (not sure what specific kind beyond that), and overall it's worked very well for me. Mine happens to be a farmer jane-type suit, which I've found gives me more options for different water temps. I tend to run cold anyway, so the warmer wetsuit is nice.
I don't think that you necessarily need a hood all the time, even if you need a 7 mm suit...if the water isn't really cold, I'll just wear the farmer jane part, minus the jacket.
The zipper on the chin hasn't been a problem for me...I don't own any other hoods, so I don't have anything to compare it to. It seems to fit well, though, and doesn't bother me in any way. I second the comment about getting help to take it off...it's especially hard after a dive or two. Getting into it is tricky as well, I usually end up having to do a sort of high-stepping "wetsuit dance" to get it on.
As for storing a full suit with a hood...I don't like to fold up neoprene for long periods, so I'd recommend getting a really strong hanger and hanging it up on that...that's what I do, anyway.
