Someone asks about which subs to run, and not one person asks him 1) airspace/space available, 2) what he's wanting exactly out of this setup [DD, competition SPL, etc] or 3) what his front stage consists of to try and blend it with this new substage.
But then I forgot, today nobody builds their substage with the rest of the system in mind (blending etc), they just stuff the largest diameter cones in their trunks as they can, because someone else told them that was the right decision.
Having said that, you need to answer those questions yourself. But I will say, given the choice, Id generally chose two 12's over a single 15. More cone area plus two motors to divide the heat between. In other words, all other things being equal, two 12's should displace more air (louder), dissipate more heat (longevity) and should work each sub less given a specific output volume required (less distortion at any given output level). The only real disadvantages to dual 12's would be it would cost more money, and its sometimes harder mounting dual 12's than a single 15 given the space available.
