I am a big fan of the Leathermans I have the old Super Tool and EDC it. I have not really had a chance to handel the Swisstools, but everbody seams to like them, try to make a list of features/tools that are most important to you and what you will be using the tool for most of the time, also think about what you don't like about your current tool and what improvements need to be made. Then compare the two tools and see which one fits the bill better for YOU.
