Here is my personaly opinion:
I think they both suck. Please, no flames. This is JUST my opinion.
I have experience with both, kind of. I have had FIVE Endura's and 1 Native. Out of the 2, the Endura was definitly the sturdiest. I loved the serration pattern, it seemed like it could cut for ever. However, I broke the tip off of all five of my Endura's after several months of hard use...I mean really hard use. So, I guess they did alright considering the abuse they received.
The Native however just plain sucked. I got the knife and really liked the looks and the ergonomics...but that was it. The action on this knife just plain sucked. It was stiff as hell, and the blade, being a spear point, was so light that it was immposible to just flick it open. ( I could do that with all of my Endura's) Then I put a huge chip in the blade the first day I owned it, I just dropped it on the dirt while I was doing some work, picked it up and presto changeo a chip. The I bent and broke the flimsy ass tip off the next day. Needless to say, I was not impressed and have decided not to purchase another spyderco...for now. Like you, I am not a big BM fan either so that leaves me looking for a new, tough knife that I can subject to unmentionable horror's!
As a side note, I do also own a Cold Steel XL tanto voyager, and it has withstood 1000X the amount of abuse as my spyderco's, it's even better since I cutoff the integrated clip and put my Natives metal one on. However, I cannot recommend it either, because it has the same faults as the spyderco.(i.e. second rate steel, and Zytel handles) I can say with out hesitation that I will NEVER by another knife with Zytel.
Anyway, that is my take on things, take it or leave it.
