One of my peeves with my Spirit was the mirror-shiny finish on the pliers handles.
It looks awfully pretty in the store showcase, but it's slippery as heck in practical use. I took some coarse emery cloth to it. It's not as pretty now, but it's better otherwise.
Other than that, I wouldn't hesistate to carry a SwissTool or Spirit into the bush. But overall, I still prefer the Leathermans.
