I don't know whether the parts are the same in the UK, but I've found Bendix or Delphi to be pretty good, Brembo disappointing. A word of caution though; when I changed the rear pads on my car, when I collected the Bendix pads, they were lacking the pip on the backing plate which aligns with the slot in the caliper piston. The store also opened a pack of Brembo pads, and their own brand, and neither of these had the pip either. In the end, I bought Pagid pads from another store, these had the right pip and were supplied with new shim plates (the thin folded plates that clip onto the yoke that the pads slide along).
Eventually, I decided to buy the genuine Hyundai pads when I saw a set at a reasonable price on eBay. The quality is a lot better, the backing plate is stamped very cleanly and well finished. I'll keep the Pagid pads for the next change after the warranty runs out.
Whatever you buy, check whether new shim plates are included. If not, you will have to buy them separately at additional cost.
