MCA or MCA-Style joysticks seem to be the standard for Australian arcade machines, 99% (maybe even 100%!) of the arcade games I've played in Australia have this style of joystick.
I do agree that they look a little ugly but they feel quite nice to use and they are the only ball-top micro-switch joysticks I could find.. but they cost about AU$25-30 so I order ball-top Wico leaf-switch joysticks from the US for about $20 instead.
Go to any place that has a few arcade machines (Timezone, a Bowling Alley, etc.) and you'll be able to test these out yourself, if I was to buy micro-switch joysticks instead of leaf-switch I would use an MCA style one over a bat-handled one.. However this is partly due to the fact that being from Oz I've never used a bat-handled joystick, so it wouldn't seem right!
Personally I think the small ball top is a little more comfortable that the big ball top on Wico joysticks, others may disagree though.
