bit of a late comment, as im just catching up, but as others have said, if youre trying to gauge funky from releases, then youre not going to get v far. you need to be listening to all the sets really to get a decent idea about it. but if you compare it to releases that are actually out, then yeah, of course night slugs and that lot are going to have an advantage. i dont think its really fair to compare the stuff house/funky has inspired to funky itself, but if youve always been into the more 'progressive' end of stuff like blackdown has been far as i can tell, then yeah, youre going to be more into numbers, night slugs and that kind of thing compared to say, mad one or champion and co. funky (or insert other scene name) is the engine powering night slugs and them anyway. without it, they wouldnt have the chassis for a lot of their ideas.
edit - as for the perfect ill blu tune, blu magic is pretty much it. i think they have quite a few in fact.
