I've done it both ways but find the wrist mounts easier to use. Consider, its the end of the dive and you are ascending the anchor line. Its surgie, and you want to ascend slowly and make a safety stop
Hand over hand up the line, you have one hand kinda busy with the bc deflate, maybe a camara in the other, and both on the anchor line. I find a glance at the wrist mounted depth gage (actually an air integrated computer now...) easier than grabing the console and checking. Besides I am getting older and my vision isn't what it used to be, but I always know where my wrists are...
Some people manage to make their consoles, sit conviently on their chest, but I always have lights, spare lights and other stuff there already. I rarely check my SPG (though i have one) as the tank info is on my wrist computer too. Remember you may have a depth gauge, a compass, a SPG, and a watch. Most likely the watch will end on you wrist anyway. I often don't carry a compass and sometimes carry a timer with split timing instead of the watch. I don't want to rearange the console.
good luck and have fun diving
