The Manix LW is a great folder, but to me it just feels a bit flimsy. I'm not saying it is flimsy (it isn't), just feels that way compared to a standard G10 Manix.
Some complain the jimping around the Manix is too aggressive, but I don't find it to be so. Actually I like it.
Like trevitrace says, some complain about the Para2's handle/blade ratio. I don't see it as a problem, though I will agree that there seems to be room for the blade to be a wee bit longer. I freely confess to being a Para2 fan.
As redbull says, the Manix CBL can feel stiff and requires a thumb and forefinger grip to manipulate it, and I also have no problem doing that. Yes it's way stiffer than BMs axis lock, but to me it's very usable.
OP, your right, they are all great folders. Just to cloud things a bit more for you, have you considered a Manix XL? Many call it a pocket hog, but I have no trouble EDC'ing that bad boy, it's definitely my favourite Manix. Does need a deep carry clip though, and the clip is also needed to grip with your fingers to enable one handed closing due to the size of the handle.
