To be absolutely honest with you, I use gauge mode a) because I feel I can do so safely, and b) because it gives me the information I really WANT (depth and dive time) in the biggest numbers in the center of my screen. In computer mode, my computers put the dive time in tiny numbers in the bottom right-hand corner, because it's not really important, is it? What's important is your NDL time remaining, which has the big number/center screen position. That annoys me, so I use the display that gives me the information I want and use where it's easiest to see.
On our trip to Cozumel this spring, I did put the computer back in computer mode because of the amount of diving we were going to be doing, and the depths involved. The second day, I forgot to set it for 32% and bent it (and my backup, which was in my pocket, which I also forgot to set). That was the end of computer mode for me.
