I've used many multi-tools for bush-crafting; I don't know if you know the Mora knife series? my Mora knife used to be my main bushcrafting knife, but now I use my Swiss army tool as my only knife, the Swiss steel is in-comparable for a multi-tool, and there's many different types. It's the only one I would recommend now.
Ive always used a leathermans feel naked without it but you need to think about what you want to do with this tool and what do you need the tool to do what blades douse it have is the size and weight OK for you because even the cheep tools work well if used properly
I like Gerber too, but the leatherman x2 that I have doesn't accidently pinch my hand when using the pliers. Gerber has good steel, but they are a bit short on what blades and such they come with. I have a Leatherman wave and a super Leatherman. Never had a reason to complain about anything when using them. I also have a Gerber, which I have owned for about 15 years.
Leatherman, Gerber and SOG all make good tools. The trick is deciding where the tool will be primarily used, such as for outdoor sports or in an industrial environment. Outdoor tools should have a good knife blade, saw blade, file and can opener. Work related tools may need to emphasize screw drivers and wrench doo-hickies. I have two, one for work (Gerber) and one for play (leatherman).
