I like them both. The ZT 550 is discontinued. There are still some at dealers and you can also find some in the for sale section here. The interesting thing about the 550 is either you can open it or you can't. For some reason some people (about 1 in 5) have a horrible time opening this knife. They either push in on the lock bar or try to push out on the thumbstud. If you have held one and have not had this issue then I would say this might be a good choice.
The triage is one of the best Benchmades out there. Some complaints are that the scales are too grippy. I personally think they feel great. The N680 Bohler steel comes wicked sharp and the knife keeps a great edge. The bonuses of course are the seat belt cutter and window breaker!
I think the question needs to come down to what you want and which one you like. Do you want an Axis lock or frame lock?
Good luck with your decision!
Thanks that actually helped a lot cing side by side pics.
