I agree, the dedicated scissor tools are generally the best. The best of these is the Schrade MiniChip, IMHO; they're big and rugged. Next on my list is the SOG CrossCut, followed but the LM Micra and Squirt S4.
My favorite "accessory" scissors are the ones on the old Wave (and Pulse, and PST II); sturdy, long "bite", excellent spring design (lever off backspring, no flimsy leaf spring).
The new LM scissors aren't near as nice. They're a LOT shorter, and lateral pressure to the side the spring is on, can cause the spring to "jump" the blade. However, for their size, they do cut surprisingly well, and the spring isn't a problem if you avoid pressing on the spring side. Still, I wish they'd just put the old Wave/Pulse/PST II scissors in there!
The SwissTool scissors are huge, and cut very well, but I've always hated that damn Victorinox leaf spring! It's just not strong enough, and doesn't open the scissor far enough to make full use of their size. I haven't seen the Spirit yet, though, but from the description, it sounds like they've remedied that weakness.
Gerber/Fiskars scissors are the worst of the major brands, in my experience. They're always too short, too wide, uncomfortable to use, and have NO return spring. The curved cutting edges are supposed to be an advantage, but I prefer to use different edge angles to suit the job: the steeper angle near the pivot for maximum slicing of tough or thick materials, the shallow shearing action near the tip for more delicate work. The Fiskars design takes that away from me.
The scissors on the SOG PowerPlier is like a combination of the Gerber and old Leatherman designs; the blades are medium sized and straight, and the spring is strong, and held captive in a slot to prevent slippage. Action is a bit rough on mine, but then mine has the matte black oxide finish, which isn't exactly smooth.
