I didn't have a problem with the Yellowstuffs, but I'm now running Bluestuffs - although only got 1000 road miles on them. They're not making any noise as far as I can hear, and they're working fine from cold (0ºc on Saturday morning), but so are my Michelin PSS at the same temps (once the tyre has warmed up over 5 miles or so).
Only ever tried the RS29 Pagids in my AP brakes (330mm, 4-pot, braided hoses, DOT 5.1 fluid) on my Corrado VR6, and I thought they worked quite well, but at over £250 for an axle set every 3 track days, I decided to try something else, so tried DS2000, DS2500, DS3000 and compared to the Yellowstuff found them worse, worse, and comparable respectively.
My last set of yellows lasted me 30,000 miles - including over 50 laps of the 'Ring (fronts had 3mm pad material left, rears had 8mm) - but I'm not particularly heavy on brakes and prefer to come of the pedal earlier to settle the car before a corner, than waiting until the last minute to slam on (but then I've never had an on-track accident since I started doing them 15 years ago). After all it's only a track day, not a race - and most race pads are meant for 20-40 minutes of (ab)use at a time.
Different pads suit different driving styles, and I know plenty of racers (from a marshalling standpoint) who use EBC yellow/blue/orange pads as a budget (i.e. 50% cheaper) option over Pagid/Ferodo - and they still manage to be competitive.
