Worst f/o I flew with, wa ex US military fast jet jock, ex widebody jet Captain, who I wrongly assumed would be up to the job and more. I learned something that day.
Best f/o was a cadet with a years experience on type. We had an extremely difficult day but his training and "common sense" provided me with as much support as I could have expected from any colleague on the flight deck. (be that Captain or F/O).
I think we have to accept that different regions of the world operate differently. It does not make one country more right than the other.
