First of all, that orb is extremely loud, and doesn't have the best performance. Second of all, why do you care about the connector? And finally, you asked a very complicated question 😉 You need to read some reviews on the web (FrostyTech.com, AmdMb.com, AmdZone.com and others) to really find out which one is the best... I don't think anyone here bought several heatsinks just to evaluate them...
Also, search forums for similar questions.
