I don't know about the Camillus knives, but I do own the Flash I and the Mini Fast Draw. Given your choices, go with the Flash I. The AUS-8 steel is much better than the high carbon stainless mystery steel Gerber uses, and SOG's build quality is better.
If you're willing to look at other options, I'd also recommend the Kershaw Chive and Scallion (assuming fairly light use). Granted, it's 420HC steel in these, but Kershaw does a decent job on their heat treat, and the build quality is top-notch.
Another one to consider might be the Spyderco Dragonfly2. Around the same general form factor, but up a notch in price point. You get great VG-10 steel and rock solid construction. (but it's not A/O)
