I'll organize my thoughts, and make my choices, based on number of "blades".
1 blade: Florist with chisel ground sheepsfoot (but Alox Solo is a close runner-up)
2 blades: Pocket Pal (I'd really like a Victorinox Settler here, but I've never seen one in person)
4 blades: Alox Electrician (trading can opener for sheepsfoot is big plus for me)
5/6 blades: Alox Farmer/Farmer X (haven't handled a Farmer X but the idea of adding the scissors certainly appeals to me)
More blades: Fieldmaster (don't have one, but lengthy cost/benefit analysis suggests it's the best SAK for me)
(FWIW, I currently carry a Minichamp every day, mainly for scissors and pen, but it's little so I'm figuring it doesn't really count in a top 5 list.)
