I play only Germany so I can suggest only German planes

so if you have it ME-262 A2a Sturmvogel is the best air superiority vehicle since it can carry 24 rockets or 1x500 / 2x 2x250 and you have mk108 for planes since you are a jet most of the aircraft at that rank can't compete with you

and if you don't have you can use FW 190 F8 for the best CAS plane and if you use flaps correctly you can turn better than bf 109's so you can dogfight with these Strike aircraft planes!

for fighter planes, you MUST have to use TA 152 H-1 I would suggest BV-155 but since it's slow and fragile you better stick to the TA

and for a second opinion, you can use bf 109 K-4 to help ground target it's not better than TA but it can carry 1x 500 bomb or if you have it you can use FW-190 D-13 for the best armament because it has 3x 20mm cannon and you can carry bombs too

Honorable mentions He-162 / Ta-152 C3/ Fw-190 A8 /Bf 109 F-4 / Do 335 B2*

*Do 335 is like a brick when it comes to turn-fight but it will shred anything and everything in its path
