Maxx is my EDC as well. I have one of the older, thicker framed ones, still easy to forget it's there and I find the extra length to be more of an asset than a hindrance. (in daily normal circumstances, not just tactical perspectives) I have a tiny single bladed Camillus pen knife I also carry if scaring sheeple should become an issue. The new thin framed ones are especially light and friendly. It's all been said about the sizes, etc. so I won't rehash everything but if the choice were mine, I'd go with the Maxx. It's my favorite knife for the times when I can't carry my BK-5. (then again, I realize my tastes are quite odd at times) If size is even remotely likely to be an issue, I'd go with the ATR.
