I have all DIN regs, and greatly prefer that connection method.
BUT I would make certain you have easy access to DIN tanks on a regular basis if you decide to go with DIN regs. I own many tanks, so DIN is not an issue for me, but if I had to rent tanks, the numbers available to me would be much smaller, and fewer shops would have tanks that I could rent. So this answer depends very much on your local area and what's available... if there are only two shops that rent DIN, are you ok with that?
I don't like using my DIN-to-yoke adapter for the reason others pointed out... it makes my first stage stick out more and hits me in the back of the head. (Sooner than it would otherwise, at least) For one or two dives, no big deal, but for a serious trip where I will do lots of diving, that gets old really quick! (Especially since for dive travel it's frequently warm water where I do not wear a hood, unlike locally where I always have a thick hood) For any trip longer than 2-3 days, I'll convert my reg over for full-time yoke.
