For your driving style, I'd look at something that's either high-efficiency or quiet, and long lasting. PS2s are very high performance, soft tires, and you wouldn't be getting much out of them for their really high prices. Michelin as well as others make fuel-efficient tires. Tire Rack did a test on these tires a while ago to see which one was best, and that would be a good place to start your research.
Be careful with tests though: they only say things about the tires for the conditions of the test, so read and consider the fine print carefully. For example, the Hankook vs. Michelin test was for short term use: they had a really short track. Some tires will heat up faster (perhaps because they have squishier sidewalls or something else), and then fade really quickly as they overheat over extended usage. How a tire meshes with a car's suspension system also has a huge effect on the tire's efficacy.
