Need rotor recos for '02 Yukon Denali

[alvocado]

While doing my brake job this weekend on my '02 Yukon Denali, I discovered my rear rotors were pitted and had some scoring due to a fully worn pad. I took them to get turned but the shop indicated the pitting and scoring was too deep. Net, I'm shopping for new rotors.

 

I had decent experience with the AC Delco OE rotors; these were the originals with 55k miles on them and if not for the nasty OH winters and my letting the pad wear too thin, I probably could have gotten another 40k out of them. A family member who works for Delphi told me that Brembo Rassini makes the Delco rotors. So do I buy a set of Brembo OE replacement rotors which run about $93 ea (much cheaper than the Delco replacements) or should I look into some Powerslot slotted rotors for about $10 more per rotor? I'm not interested in going too high performance but wouldn't object to improved braking provided I don't sacrifice rotor life.
