I've used their stick pack equivalents and they have always given me the most ampage. I never run my packs down that low, so the output ampage is my main concern rather than how long I can get that ampage as a constant. This sort of thing is always subjective. Different chargers/dischargers measure differently and many of the manufacturers measure their outputs differently. You also get completely different readings depending on the temperature that you run them at. I've used all sorts of Lipo's, but most of them are made by just a few different companies an then just re-branded. Kokam are the best in the world in my opinion, but again, it all depends on your application. I've run 6S set-ups at 240amps constant and always had to pre-heat my lipo's to get the best from them. All I know is; the LRP range has always given me the best 'punch' and I've never lost a cell yet!!
