I like both honestly.
For me if the bezel turns, any hour can be set to correspond to the GMT hand allowing for timing second time zone quickly and/or for multiple zones. I suppose you could unscrew the crown and move the hour hand, or count, but a moving bezel on a GMT watch is easier for me. Unless I just am missing something?
If I was actually diving I wouldn't care what time it was in Hong Kong and would care more about my decompression zones and wouldn't be looking at the above white/black reference for diving. Besides the only diving I do is into datacenters.
