As a 30 year mechanic who's done well over 1000 sets of pads and rotors (about 10% of those on vehicles that were mine or that I drove regularly), I can tell you this is normal for a few days, but should fade away completely within a week, dependent on your driving conditions of course. If it doesn't then you've got another issue, could be unrelated, or could've been poor workmanship in the brake replacement. I've used all sorts of modern brakes, and they all have at least a little bit of that smell when they're new for the first few days. I saw you mentioned BrakeBest, they're cheap, but decent quality, I try to avoid them because it's usually only a few dollars more for a much better quality set of pads. Any brake pads with a ceramic composite compound (which are most nowadays since asbestos is banned in them in the US) require a bedding procedure, though some can be supplanted coating the pads in an additional resin and baking them in an oven before installing them on the vehicle. It's best to follow the pad manufacturer's recommendations for this. Semi-Metallic pads usually do not require bedding, but do have a break-in period. Regardless of the type, what you're smelling is the binding resin in the friction material of the pad (the resin that holds all the bits of the friction material together in one solid piece) basically melting and depositing a layer onto the surface of the rotor as some of the friction material burns away, and this is essential for proper brake function and performance. Once the layer of resin is fully formed on the rotor surface, the smell should go away as the layer of resin on the rotor surface will act as a sort of lubricant to keep the friction material from burning as you brake normally.
