i have a hayward super 2 pump and never had a problem besides having to replace the motor after 4 years of use,but thats normal with every brand.
i have seen 1 year old pumps from other manufacturers go out .
next time the motor dies i am replacing it with a pentair intelliflo or jandy ePump.

i would go with

1-pentair
2-jandy
3- hayward

What you would need to realize is that EVERY single speed pump put out by a major brand had the same motor and that is one made by AO Smith. You are really not making a major decision when buying a pump. Avoid off brands that are not Hayward, Pentair or Jandy.
