Stock rotors are actually quite good as rotors go. They can be turned at least once if you don't wait too long to do it. Just paint the centers so they won't rust. If you don't want drilled or slotted, that's what I'd buy. It's OEM, and cheaper than OEM doesn't sound like any kind of bargain to me.
I bought some PowerStop cadmium-plated rotors for a car a number of years ago and was quite happy. Just the groove slot, no holes. Mine were gold-colored, but otherwise same as they currently offer. The plating protects them from rust, other than that I'm making no claims of why that's good. I didn't own the car long enough to need them turned, which might be a concern. But the plating didn't wear off in ~20K. I don't know how deep the plating goes, and a good rotor can be turned at least once before replacement.
I'd go with OEM, if it were my money. PowerStop if you want slotted.
