I second the opinion of going with stock pads with a Land Rover. Brake pads are a compromise of cold stopping power, fade resistance, dust, noise, longevity, price, rotor wear and with 4x4's, wet performance. The stock pads are the best compromise for the driving conditions that most of us will experience. If you're always towing a boat, horse box or a 25 foot Airstream, your needs might be different.
IMHO, most of the improvements that performance pads offer are of little value particularly, fade resistance which is usually a compromise with cold stopping power. Nothing is worse than having brakes that need to be heated up before working. How many times in your life have you ever smoked your brakes? Every day, your first 5 or 10 miles of driving are with cold brakes. Two brake stories before I go: My Dad had a BMW 750 iL on which he put drilled rotors and some expensive hi-po pads. He lived on a fairly steep hill with a school bus stop at the bottom. The first morning after the brake change, he nearly took out five kids at the bus stop because the brakes offered virtually no stopping power until they got hot. He got so annoyed with them that he changed the pads back to stock after a month. Story two: About ten years ago my wife and I met some of our friends at Yosemite for a weekend camping trip. She was driving our Disco 1, I had an '86 911 and our friends had a rental Pontiac. We decided to take the Priest Grade short cut on the way home, if you've been there you know how steep that road is. By the time we reached the stop sign at the bottom, the Pontiac's wheels looked like they were on fire and smelled like it to. The Land Rover and the Porsche were fine. Moral of the story, high quality cars have high quality brake pads.
