For my hunting rig I use a 11.5" Doinker Cabon Elite. The extra length of the stab causes the bow to hold steadier than with the 4" stab I was using before. While I am not going into the woods with a 35" stab on my bow like I do on my target rig, the concept is the same. Longer stab = steadier hold.

The vibration aspect to me is secondary to the extra stability in the hold. This is the reason they are called stabilizers and not vibration absorbers. Your need for the vibration removal is also a function of the bow you shoot. Some bows are pretty naturally dead in your hand, while some feel like a joy buzzer. If you have one of those bows that has quite a bit of vibe, then the vibration reduction capabilities of the stab can make your shooting that much more enjoyable, however that in itself will not effect the accuracy.

The best thing to do is go to your local shop and try a couple out.

Some of the better ones I have found are the Sims products, Doinkers, and Vibraflex Isolator. Others will have their personal favorites, however it really come down to a matter of preference.
