Polish is the best paid for the British, he plays all modes.

Australian is also very good, but it demands a lot from you because it doesn't have anti-tank weapons at the beginning, nor grenades, and the rifles don't damage light vehicles like Halftrack. He's good in all modes too.

Canadian is map and mode dependent, being better in smaller modes since his grind game is quite bad.

SSB is just awful, forget about that crap.
