Let me first admit my bias so you can be the judge of if you agree or disagree with me...Personally, I would carry a Frost Cutlery piece before any MicroTech and sold all of mine back around 2006 after MicroTech made is clear how they feel about the people who buy their knives. So upfront I am admitting my bias, but I personally have zero desire to give a company a penny of my money that shows what I consider to be completely unprofessional conduct, apathy, and mistreatment of its customers.
I'm not a fan of tantos myself, but get the Emerson. MicroTech is not a good company to deal with...if the knife needs service, you're better off selling for a loss than trying to deal with them, IMO. MT also isn't exactly a very consistent or predictable company, and the use of things like proprietary screws which you need to spend $50-100 on a screwdriver you cannot find to tighten a pivot is to me, not a plus. It's a shame given they can produce some seriously awesome designs, but a product is only as good as the people standing behind it, IMO.
If you like MicroTech's style, check out Guardian Tactical. You may like the Helix. ProTech makes very good autos as well and they stand behind their products 100% and their dedication to their people is comparable to that of Spyderco. If you have an issue with a ProTech auto, you won't have to worry about a 6 week to 6 month wait only for the problem to be partially fixed or not fixed at all.
