I dive a back inflate and yes, it CAN push you face first at the surface but if used properly it won't. I found this out on my first OW training dive. I had entirely too much air in the bladder which pushed me forward.
My instructor had me let out some air and then lean back like I was sitting in a Lazyboy recliner. From that point on I have not had an issue.
It is comfortable unlike the jacket style which I find, like @Marie13 and many others, squeezes and makes diving a bit uncomfortable.
Plus, having the bubble on your back makes life easier as far as I am concerned.
