I like the Para 3, but the Native 5 fits my hand better than any other model. It is the the most comfortable in hard use when real force is being applied. This is compared with the Para 3, PM2, Military, Sebenza and Inkosi (large and small). I don't have the G10 version, just the lightweight. Some have the standard clip, some have the MXG deep carry clip. It has a smaller pocket profile without the hump in the blade, so it is not as much of an issue reaching in your pocket for other things that may be there. And in my opinion the lockback's good detent is a positive aspect. It won't come open on its own if it is dropped or if there is hard impact (like an accident).
Of course, YMMV with how it fits your hand and lock preference, but it woks for me.
I really like how Rex 45 sharpens.
