I carried a Gerber for about five years, and got rather attached to that thing. It was fast on the draw, and I knew where everything was. When it walked away, I wanted to get another one, but the knifeshop I used then wouldn't cut me a deal on the gerbers, they would on the Swisstool. I still would call the gerber my 'favorite', but I feel the swisstool is a better tool.
The Swisstool is more solid feeling, all the toold lock, and it is larger. I removed the studs from my tires (all four wheels) yesterday, with my swisstool. I tried another pair of needlenose pliers I have, but they didn't offer the grip I needed, the swisstool did. The swisstool is more comfortable to use than the old leathermen, and doesn't pinch as readily as the old gerbers. It is big, and bulky, and slower than the gerber, I don't know if it will loosen up like the leatehrmen I've seen.
The sole downside I see to the Swisstool is the type of lock. Them itty-bitty buttons are not easy to access in anything other than an office environment. I have, with difficulty, operated my swisstool in environments ranging from -40 to +100, and rain to mud to snow. With bare hands, it works well, but with glvoes on, it becomes difficult. At -40 it is nearly impossible to use, because you have to remove so many layers of glove to operate it that it becomes hazardous.
That said, I still like it, and don't know of a multi tool that would be easy to use at -40. Come to think of it, I don't know of anything easy to use at -40. I would simply prefer an easier lock-release device.
