I'm pretty happy with my 205/50-15 Azenis. They're very grippy, solid (no flex), responsive, and street legal. They are meant for a 15x6.5" rim, so I wouldn't expect their best results from mounting them on your stock 15x6.0" rims.

They are a bit heavier than normal tires, but their cornering and braking performance more than makes up for it. They're probably not the best choice for drag tires though.
