I guess that concerns me since I too voted for Pirate Man
Well personally, there's a strong visual element to my preference and Mega Man 8 / Mega Man & Bass (which esssentially use the same graphic style) simply have much better looking Robot Masters with more unique styles.
In comparison, all the Masters in the first game basically looked like Mega Man with custom helmets and different colors, and it wasn't until Mega Man 4 or 5 that we truely started to get more differentiated designs.
Nowadays, they all have different proportions and truly unique styles and body parts. Take Ground Man for example; he doesn't nearly look like anyone else and instead looks simlar to be a drill tank in a humanoid body. Pirate Man looks like a robot pirate, while Astro Man looks, well, like a goofy robot torso stuck to a giant bowling ball.
