I like the first one, but I don't like the button on the right. I'd delete that button, move the spinner further right, space out the joystick/button group to something close to slagcoin's measurement layouts (if not already), and also move the joystick/button group a little further right as well.
Here's my Arkanoid panel. When I first started playing I would use my right hand to control the spinner, and left for 'fire'. But after playing with a joystick more (I had my Arkanoid running long before I had any joystick/button game running), I naturally use the spinner with my left now.
Normally I'm a fan of options (ambidextrous controls for example), but in this case, with this being a bartop and space being limited, I'd have a preference of not feeling crowded on the CP while playing.
