I was experiencing the same problem since I just got meteoric dagger. Like Napol said, Dmg gap, yes. Dps gap, not really. Haste lix will help just as much with a fast and weaker weapon as it would a slow and stronger one. Don't forget with a haste lix your meteoric bow will be doing close to 1 hit per second. Even with my meteoric dagger and haste ring it keeps a constant smooth hit animation, with a haste lix, I am pretty sure the met bow would do the same or faster. Haste lix works for both bows, and each have their pros and cons, but overall I say meteoric dagger because it has a pro that the adamant does not, its free.
Rangers can have some pretty amazing dps. 60% of dps is speed, 40% is damage. Just look at the cruel knife with 1400 speed. It does almost as much dps with an elemental offhand, if not more, than a meteoric dagger with the same gear.
On the other hand, the adamant bow uses the best factor that bows offer, big melee hits. The adamant bow takes advantage of this, but it works better than a meteoric bow only if you are a str build, and lets face it, no high-lvl ranger is a str build unless you are endgame.
Honestly, I can't decide, but this isn't a world where there is infinite gold in your bag, so go meteoric.
