Been reading for a while and there are different opinions.
I will keep the rotors and just change pads.
See R1 concepts page a there are a lot of them!, axxis, posi-quiet, hps, etc.

I drive a little hard to work daily (75mph on highway only), so install stocks or any other brand?

Suggestions welcome

If you're mostly in that speed range, the OEM pads can handle several hard stops without fading, and it works the best for cold stops (i.e. say you're at 75mph without hitting brakes for 5 miles, then have to stomp on the brakes real fast, the brakes will work right off the bat).

Some higher performance pads will work better for more repeated high-speed stops, but your cold performance will suffer. It's always a compromise.

My vote is for OEM.

I'm going OEM too.
