I can only speak for myself and am close to pulling the trigger on the Contego. My desire to get it is the steel (M4!!! --- coated so as to be water resistant), 4 inch reverse tanto blade, it's newness, being tactical as well as having some utility with that M4 blade (no I would never be in a knife fight!) and being able to get a good price --- especially on a knife with M4 steel.
But I'm still not sure what is best as no nearby dealer has a good stock of Benchmades.
The Rift is on my list, too --- maybe the nicer knife. Even the 940 (in green probably) looks good and is really popular and lightweight (S30V steel!)
What really got my interest started was the Bedlam (154 steel). The looks! The G-10 on it! 10 inches! But the blade is seemingly purely self-defense. My friends would be impressed (which is good) but I heard the blade is a bit weak (0.125?) and could wobble a bit. The Contego complaint seems to be the handle --- the G-10 might be a littl rough cut. The Rift is probably better in this regard. And well priced.
I'm not that familiar with the 530 but it looks good. Slim blade probably means sharper.
It seems the blade getting alot of press is the adamas (275). The D2 must really be well done. Great deal, too. Extra strong axis lock (800lb!)as has the Contego (I believe). But could be a bit big for me to pocket.
A part of me still wants the Bedlam if only to collect. The 940 is really popular and has received acclaim form several. The 950 seems like the best all-arounder (the gray/black combo seems quite handsome, too). The Contego could be a bit of a risk. The adamas seems to be super well liked. The 530 could be the sleeper. It's too confusing and I want them all!
Good luck and enjoy the hunt!
