Generally ZVS turn-on of MOSFET is considered as a good feature in power converters. In H-bridge converters, the MOSFETs in a switching leg operate in complimentary manner. So, when one device is undergoing ZVS , it is certain that the complimentary device turn-off happened when it was carrying a non-zero current. Because, only after the device is completely off, the diode in the turning on device can conduct. This would result in turn-off loss in the device. Why ZVS turn-on is still considered as favorable feature even though it results increased turn-off loss in complimentary device.
