The benefit of push to level off is it's a one step solution. V/S zero requires 2 steps. An alternative, but still 2 step, solution on a Boeing MCP is to press Alt Hold, then pause, and then press it again as the aircraft's V/S approaches zero.
In a perfect world for me, the Boeing MCP would have a push to level off feature, and the Airbus FCU would have a V/S thumb wheel.
I won't hold my breath.
