Being of simple mind I like the bypass arrangement that has three valves so it is obvious where the flow goes.
Shut off the valves at the Water Heater and open the bypass valve for winterizing. Reverse the valve positions for normal operation.
But then you miss out on the buzz and squeal from the check valve, not to mention the fun of replacing it when it fails. Also, the check valve saves some hot water when it reduces the flow.
