A good aftermarket belt drive is untouchable. Chains are a joke in comparison, and gears are for rednecks. Gear drives aren't all that for accuracy either, they wear out! As mentioned above, they introduce harmful harmonics into the valvetrain that wouldn't otherwise be there, and in my opinion, the valvetrain is the most important system in the engine.

Chains do work the best for what you pay, and that's what I'd recommend for 99% of the populace, the other 1% benefitting from the dead-on timing and RELIABILITY of the belt.
