Don't know about the Gerber, but I have the Alpha and I have affectionately dubbed it the quickest waste of 90 bucks I have committed thus far. There are some major, imho, design flaws with this knife.
First the handle is awful to grip when it gets either the slightest bit cold or the slightest bit wet. It's design provides no insulation between the cold-absorbing steel and the fingers. Plus, the smooth as glass resin slabs that are inset from the edges of the steel are hard to grip when dry, when they get wet, they slip unbelievably. The ridges carved into the top for your thumb don't help that much in keeping the blade from slipping and actually hurt the thumb with any amount of use.
Also do you see that nick where the edge and the ricasso meet? You would think that the blade is edged all the way to that nick when it fact it is not. The edge just kind of falls away above that nick where the die cutter drifted away from that blade. Buck didn't ante up the extra little bit of money to come back and continue grinding the edge up to that nick. They left if for you to deal with when you are try to start a cut at the point just above the nick only to waste energy trying to push flat steel through whatever it is you're trying to cut.
IMHO you would be much beter served purchasing the Buck Vanguard. It performed for me well recently on field dressing a 350 lb. hog and costs half as much as the alpha. I'm not sure what Buck is trying to get at with the Alpha hunter... When you look at it, it's really alot of quick, easy, slapped together work given a shiny package - maybe it's meant for the yuppie hunter, I don't know....
