It's always interesting to note trends among different forums. Here, I think we tend to like Waves and Swisstools. At tacticalforums, they like Swisstools. At Jeff Randall's forums, those survivalist types like Gerbers.
I divide my multitool needs into what I usually need (a regular-sized tool that's easy to carry), and what I sometimes want for harder work (a large tool).
My fave small tool is almost certainly going to be the LM Pulse. It's the same as my current favorite, the LM PST2, with the addition of locking tools. In my mind, that is almost the last word on this size tool. I would like exterior-opening tools, Swisstool-style, especially since this format provides comfortable handles (the PST2 hurts like hell when you use the pliers hard).
For a big tool, I remain firmly undecided. Forget the new Gerber, even the 600 series has a great choice of tools. The new Gerber looks awesome, I'm just waiting to see if it's too big, and how well it's manufactured. I love the Wave, just wish the screwdrivers locked. I've found the one-hand exterior-opening blades to be more handy than I thought they'd be. And the Swisstool also is just great, love the exterior-opening no-clumping features, just wish the screwdrivers were done right and it had scissors.
My general theory on this is, unless you have some huge need for some certain feature or other, whether you get the Wave, Swisstool, or Gerber, you'll be happy.
