I've had both large and small Barrage, and a Mini Presidio. That last one is a good solid knife, with decent ergos. I would not put it at the top of my list, but would never discount it either.
The Barrage has pros and cons. I have never had, nor seen (or in this case, heard) a knife with a more resounding crack when opened. Very, very satisfying, but I would not use this in public, for that reason. There is a lock, which makes this knife: a)an awful lot safer, and b)a nuisance to open. You have to click off the safety before opening.
The ergos are quite good, but the handles feel very, very cheesy. This would have been a much better knife in G10.
Have you tried the Benchmade Bone Collector? The handles are the best I have ever used, period. My edc is a small Bone Collector, with a blade taken from the Mini Presidio. The best of both worlds.
