Subs are kept at or near sea level pressure internally, that is why they need such thick and strong hulls to hold back the pressure differential. Airplanes are the opposite, they are kept pressurized to comfortable altitude equivalents so you don't black out on your way to Las Vegas.

Scuba divers are subject to the actual pressure of the water. Heck, you can feel the pressure when you dive into a pool and that is single digit feet. You wouldn't even notice the 100 feet of air compared to 8-10' of water.
