The only thing that I dont like about the barrage is the assisted opening. Sure, it flies open fast (but really no faster than a manual axis lock folder...), but closing takes a bit more effort since you have to overcome the spring tension. I find if speed and ease of use is what you want, you're actually much better off with a good manual knife.
With that said, the barrage is an excellent knife overall and m390 is a great steel. Truthfully though, if you can deal with the fact that it's not stainless I slightly prefer cmp-m4 to m390. Edge holding is about the same, but m4 just takes a better edge in my opinion. A good one to look at in the same price range as the barrage would be the spyderco Gayle Bradley. Benchmade also has a couple knives in m4,namely the Contego, and various limited editions of the grip, ritter grip, presidio, rift, upcoming 710 and probably a few others. Another tremendous knife with high end steel that I can highly recommend is the spyderco southard. It's a bit more expensive, but even so, I feel like it is one of the best values in the knife world. Titanium frame lock, ball bearing pivot system, flipper opening, and cts-204p blade steel which is carpenter steel's take on bohler's m390. Basically, it's American m390. Add to that, build quality and fit and finish normally only seen on mid techs like CRK. Definitely $220-250 well spent.
