Yes absolutely Austria speaks English better than Prussia. I mean, it depends on how realistic you wanna be about when nations pick up languages and which ones they pick up, but English only really became a Lingua Franca after WWII. Of course with the British Empire right there there's always been some interest in English in continental Europe but it took the double hegemony of America and the UK to really get it going. So while Austria and Prussia both had dealings with England in their history, and I can see Prussia starting to pick up some phrases for when she was training little America, I don't think either of them really started going with it until the end of the War (Austria) or the fall of the Wall (Prussia). They both speak the former Lingua Franca (French, Prussia better than Austria) and when you're in the business of Empire building, even if it fails, you want to push your own national language.
That being said, because the first modern language education method used to be named after Prussia, I tend to think she's pretty good at picking up languages. So Austria may have ~50 years on her, but they're not terribly far apart in ability. She just has a thick accent, not so thick she'd incomprehensible, but noticeable. As to which English she uses, definitely American. She and America are bros and hang out quite a lot, and until recently her people were very Pro-American so it's just altogether easier for her to practice American English. Austria probably speaks British English though, that's what is taught on the continent and it's perceived as Proper English and we all know how Austria feels about being perceived as Proper.
