This is as good a guide as any: http://www.pinkbike.com/news/brake-pad-information-2009.html
I use sintered (metallic) in winter with normal rotors.
And organic pads in summer with Shimano IceTec rotors.
My thnking being that organic pads require better heat management from the rotor and I’m a few pork pies overweight.
Sintered pads wear out rotors quicker though so need cheaper/solid rotors, and heat isn’t such an issue in cold/wet conditions.
But that’s over thinking it really, solid rotors are fine all year round, and if I had to pick one pad, it would probably be sintered.
Kevlar and other special pad materials usually try and be the best of both worlds, IME they tend to feel like organic pads with good initial bite, but still lack the outright power of sintered pads, but do last longer than standard organics. Basically there’s no such thing as a free lunch.
I use uberbike sintered pads, hard to say if they’re any better or worse than any other sintered pad, but I’ve never found them to lack power, they bed in fairly quickly* and last long enough not to be something I’ve kept track of.
*I prefer just riding a couple of miles on the road dragging the brakes alternately and pedaling as hard as I can against it. TBH the bedding in of any pads makes a huge amount more difference than the compound. If they’re not bedded in they feel crap, lack power and wear out the first time they get wet.
