Having played every iteration of D&D, I have to admit I'm a fan of the simpler "Rulings Over Rules" frameworks of OD&D, B/X and 1E/2E. It's going to boil down to how you want to play, and what your players want to play... and, to no small extent, your budget. OSR systems are a good bit less expensive than current gen stuff as they're about furthering the hobby and not about pushing product(s).
