I'm undecided. I carried a Victorinox Supertinker for a long time, but before that it was my CRKT M16-03 (old non autolawks alum. handle). I've also carried a kershaw blur, benchmade griptilian, Timberline kelly worden large tactical, Buck x-tract, victorinox swisstool, victorinox swisschamp and spyderco caly3 in zdp-189. For almost the same length of time as the m16-03 i carried a benchmade ascent. So between the ascent and m16-03 there was a lot of carry time so I guess those would be my two fav's, but the blur is coming in a close second. As far as multi tools i think my swisschamp and swisstool come in equal because they both get used a ton, the swisschamp a little more but the swisstool has its place. So i guess i don't have love for just one because they all have served me amazingly.
