"Performance" Water pump feedback

Good evening all. I'm replacing my water pump as my previous failed and started leaking. I know there are "performance" pumps out there to help flow at idle and prevent cavitation at high rpm for $100+. At rockauto I found the following two pumps that have the same improved impeller but for half the cost. Anyone use these pumps that can give some feedback?

Thanks in advance

After seeing the difference in thermostats I think they bottle neck the system. Pump all the coolant you want, won’t do much good if it can’t flow..
