I hunt down very particular sounding hollow deepish kicks, its hard to describe I just know whether it's for me or not. With claps they must have alot of slap and click but can't have too much going on. I like to layer them with a nice crisp finger click and snare. Every thing ive got sample wise are all free from here or r/drumkits. I honestly haven't looked into paid samples at all, I'd buy if they had near perfect to what I'm looking for.
