In my opinion having two pumps is better than one regardless of the make or quality although maybe less likely a high end pump can still fail and isn’t guaranteed to last any longer although the after sales service is likely to be better
having a spare pump to switch out at a moments notice is more important to me than getting the “highest quality” so I bought two pumps within my budget instead of spending it all on one.
Just my opinion as you know a return pump will most kill fail at the worst possible moment.
