As a former Nissan Master Tech, I was never really impressed with "genuine Nissan" brake rotors. They were okay "back in the day," but starting in the late-90s and 2000s, we started experiencing a lot of pulsation issues, mostly in the front, but occasionally at the rear, as well. Some call it "warping," but the actual issue is caused by "rotor thickness variation." It's almost always on floating disc type type rotors. The older style, bolted to the hub type rotors, like they used on the earlier generations of Pathfinders and Hardbody/Frontier trucks would often go three sets of pads changes before they really needed to be resurfaced or replaced. The arguments for resurfacing tend to be that you are removing layers of steel, making the rotor thinner and more susceptible to developing pulsation issues in the future. Others will chime in that the price of rotors aren't that expensive compared to the price of machining, but, of course, that depends on the type of rotor AND the quality of the replacement rotors. FYI, you can get EBC rotors that are not slotted nor drilled for our Pathfinders, if that's one's preference. EBC has on online catalog that provides good information on their products and what's available for specific vehicles. Going back to the thickness variation issues, we started seeing them first on the last generation of the 300ZX in the 90's, then it became a common issue on low mileage, A33 Maximas, but did occur on other models, as well. There have been a number of issues on some R51 Pathfinders, as well. Some suggest that it's the anti-corrosion application applied to the rotor surfaces to help prevent rusting while they sit in storage at the port of entry. Some suggest they are using a lower grade of cast iron than they used to. It's hard to say. Nissan has released several TSB's over the years. In some cases they updated the pads shims or the pad compound. In almost all cases, they recommend cleaning the hub flange surface, measuring for excessive rotor runout, resurfacing the rotors with an on-car brake lathe so that the rotor is parallel to the hub (even when installing new rotors, which seldom done in the real world), and using Nissan PBC grease, which is a copper-impregnated grease similar to "copperslip" and applied on and under the brake shims, the contact points of the metal backing plate of the pad and to the contact areas of the abutment clips. They use a thick, silicone grease on the caliper slide pins. Of course, wheel lug nuts should be torqued to proper specs when installing, which is 100 ft/pounds on the R51.
Going back to Rockauto options, I have heard a lot of good things about Centric brakes over the last couple of years. They are not an old company compared to brands like Raybestos or Bendix or Wagner, for example, but have a good reputation and are based out of California. They do have a premium pad and rotor kit for our V6 Pathfinders if you want a stock performance replacement, part # 90942030 for $110 (rotors and pads for both sides included). You can get more info on these links:

Centric provides a 90-day/3000 mi. warranty and they also make the Power Stop performance brake pads/rotors. They also have a kit for both axles for $212, # 90642044.
Rockauto also has the pin boot kits, Carson # 16185 for the front and 16055 for the rear, each kit servicing one axle (both sides).
Other brands of "stock replacement type" pads I would recommend that are available from Rockauto include Advics (which supplies OE brakes to Toyota, among others), Wagner OEX (ceramic brakes with an unusual lining design, but they stop very well and are a real bargain at their price. I've used them on my 2008 Pathy.), Beck~Arnley (which is a re-boxed, OE part from Hitachi, Akebono or Sangsin), the Raybestos Element 3/Advanced Technology and the already mentioned, Akebono ProACT ceramics. All of these pads are ceramic (like OEM) and provide new shims, abutment clips and V-springs, except Advics which I believe only supplies new shims. Some, like the Wagner OEX and Akebono, will also proved brake grease in a small package.
For front rotors, I would recommend the Wagner # BD126303E, the AC Delco Professional rotors (which are actually Raybestos Professional Series rotors, which I believe are being phased out and replaced by the Raybestos Element 3 series brakes), the Centric # 12042085 (the same ones that come in the kit discussed above) and the AC Delco Advantage, which is a Raybestos-made, coated rotor for high corrosion areas that see a lot of rust issues.
I think any of those choices should provide good options to the over-priced, Nissan stuff. If you do want genuine Nissan, try one of these sites for good prices:
