my .02c is this. The deeper you go, the colder the water will (most likely) get, and the thinner that 3mm suit is going to be. down at 100 feet in the Puget Sound I have seen 46 degree water and my wet suit was about as thick as paper. Survival at those temps are universally bad for extended periods of time. I don't agree with Weiva about drysuits being warmer IN the water, I find that I can stay in the water longer then most the drysuit divers for my first dive. The problem comes after the first dive, Surface interval, etc. I turn into frosty the snow man, while the drysuit divers are nice'n comfy.
If you stay warmer during your dives, you will be more inclined to do more dives with less thermal abuse to yourself, For these reasons I would recommend a thicker suit.
Of course the disadvantage of thicker suit is a more prevalent feeling about being in a bungee cord, and the fact that you need more lead to sink you.
