Stick with the stock Nissans if you have the stock rotors, just be sure they are Japanese. Nissans pads are usually Hitachi. I replaced brakes on 3 Infiniti's and 2 Nissans within family and friends. Brake longevity depends on the driver/car. My cars last 100k on stocks, the heavier Nissans (Murano) with a female driver, local streets last 75k.
You can gamble with an aftermarket. Gamble is the key word. If you're lucky, it'll last longer, if not it's the other way. At least with stocks you already know what to expect in terms of longevity.
If you are doing it yourself, youtube ericisthecarguy or chrisfix for basic brake maintenance. Look for their videos that emphasize caliper pin regreasing. Best of luck.
