Current Shimano OEM pads are pretty good and I'd wear them out first. I've used Kool Stop Salmon pads extensively on several bikes with both road and V-brakes and they have been very satisfactory. Durable with good stopping power, good modulation and good wet weather performance.
i have no experience with the Swiss Stop pads other than to hear good things about them but they are VERY pricey and I can't see them performing that much better.
