Paul, a neoprene drysuit (closed cell gas blown neoprene) will compress
at depth, losing buoyancy in the process.  This means that you have to
wear additional weight at the surface just to sink the suit, and then
when the suit compresses deep, you need to add gas to your BC to
compensate for it.  The additional gas in the wing increases drag and
swimming effort.  The neoprene suits are also quite bulky at the
surface, and make for fairly inefficient surface swimming, such as
might be required in a rescue scenario.

A shell suit does not have these problems, as their buoyancy is
constant regardless of depth.
