Well it depends on size of hands, as an Asian I prefer under 5 inch. It gets fit into my hand perfectly!
for me it's 3.7", that's why my last phone is Desire S, anything larger and I can't use with a single hand. I don't need a large uncomfortable brick to hold!
4.7 -5.0 is having many advantages HD rest gives more PPI results more battery life* easy for one handed use
The real question is what's the ideal physical dimensions for a smartphone. Manufacturers need to work harder on slimming the bezels.
Anyway, a 5" screen on a device with very slim bezels would be good for me.
as long I'm still using smartphone under 5 inch size....there will be no reason for me to change smartphone beyond 5 inch......it feels awkward too.....

Its depends on the hand size....
for a bigger hand 5.5 will be comfort.....
Really depends on your preference as well as your hand size so I really can't choose.
