you should just delete the switch option is just taking the space of the gba (but you'll need 2 extra spaces for the sp and micro), that's not a d-pad but simple buttons.
the psp d-pad has the right size but has rubber contacts while I prefer tactile switches, luckily the pspgo features those, so it feel right, the only hindrance is that is sunken.
dsi has a very responsive d-pad because has tactile switches a fair size and is not sunken, but the vita is something else having good response, the perfect shape and size and plenty of space around to maneuver.
