Which you choose depends on whether you want scissors or a plier. I prefer the plier with the wirecutter to a scissor since my SAK has a scissor. The Micra is a nice minitool, though. I also prefer the M3 to the M4 because I found that the tools on the M4 were difficult to deploy and next to impossible to unlock to retract them. After I tore up my finger anils trying to release the lock, I had to use needle nose pliers from my Bucktool! The M3's small screwdrivers are easy to use in comparision. However, I will concede that the SOG Crosscut/Crossgrip and the Micra are easier to use. If only there was a Micra with a plier.
