you're going to get different answers based on people's definition of 'standard'.
standard for different people can mean:
1. the most reused
2. the most sold (number of people that have it vs the number that don't)
3. the most recommended/liked
4. the design most similiar to other designs
for 1, it's a tie. they've both been used exactly once. different language variations don't count. neither do replaced older models.
for 2, I'm not sure, but in the general populace, i would argue pokers are more common simply based on price. normal people DO get scared away by a $250 keyboard purchase, but are totall okay paying $140 for a razer BW (and pokers are usually around the $110 mark)
for 3, HHKB wins by multiple light years
for 4, poker wins without a doubt. the HHKB is popular because it is UNLIKE other keyboards.
so, pick your posion
