Both pumps should be more than capable. Probably overkill. Those seem more like wash down pumps than freshwater pumps. "What's the difference?" Well, wash down pumps need more flow, higher pressure, typically don't have accumulators and most people don't care how loud they are.
For freshwater I would give more consideration to the noise level. For comparison my pump is only 30 psi max and works fine. I don't know the gpm, maybe 2ish? And there have been times that I was surprised to find the pump running non-stop but couldn't initially tell since it was so quiet. You'll also want to find the largest accumulator that you can fit. Maybe more than one accumulator in various locations along the cold water line. Many accumulators are limited to 30psi anyway.
