Nice answer Mark, that explains and makes sense now
I agree 100%, that a "full" wetsuit, if thick, is much more consuming to get in
Where a drysuit with a front zip is a piece of cake and "speedy"
For me (out VERY often all year), getting in/out is also my first and almost most important feature, just after "correct warmth" of course.
This is why I swear to 3/2 with long legs and short sleeves most of the season, as it is pretty warm and still exceptional fast to get in/out of.
Only a shorty with short legs also, is faster - but WAY too cold often, and tough on your knees if cold...
Front zip wetsuits is a no-no for me because of the time and difficulty getting in/out fast and often - eventhough they are even more flexible and sits perfect.
But they take "forever" to handle, compared.
So your dilemma makes perfect sense now, as a long sleeved 3/2 is NOT that fast.
I find it relatively easy though in a 3/2 full suit - but it IS not as easy/fast - quite a difference if you are out maybe many times on one single day
