It depends on which Hayward pump. Pump lines have different performance and quality. For example, the Hayward SuperPump is comparable to the Pentair SuperFlo but not the Whisperflo. The Hayward Tristar series are more comparable to the Whisperflo series.

But since you have AG pool, an IG pump is going to be overkill and probably way too powerful for your setup. I would stick with the Pentair Optiflo or Dynamo pump and a two speed 1 HP or lower.
