I've done watches on both. When you're really exhausted a flying bridge is somewhat invigorating as you'd expect. I still think an enclosed bridge is better all round. You can have the tools and reference materials you need at hand and have a reasonably comfortable environment which reduces fatigue - a serious problem when you can't just pull over and stop for a nap. You can still head out to the bridge wings to get some fresh air and have a look around every few minutes, which is what I used to do.
