Which heatsink? Gladiator 2/3 vs Aeroflow vs Dominator 2cu

[Temujin2k2]

So, I have 5 heatsinks sitting here waiting to be lapped and put on a Barton 2500+ AQXEA. I have a OCZ Gladiator 2 & 3, Dominator 2cu, Vantec Aerflow, an old Arkua 7528 and the oem heatsink. Which heatsink is the best? I can only find individual reviews but nothing that has a gladiator 2 vs aeroflow review. Recommendations, anyone? Or maybe stick with the stock heatsink...
