Brake pads are like tyres on that the choice is dependent on the type of riding you do. A weekend warrior that rags the bike hard on dry roads will have very different needs from the pads than a commuter who rides through all weather's.
A very general way of looking at it is:
Organic - best in dry conditions, dusty but low wear on your discs. Not great in the wet, so generally not a great choice for all weather riders.
Sintered, not as good from cold but good once warm and much better in the wet than organic. Higher wear rate on discs.
The brands etc will always split people just like tyre choice, so it's almost a case of trying them out to find what you like.
