Well, the 262 is a bit later than the Tempest, and due to the situation of the Luftwaffe, and it's terrible reliability, didn't see as much service.
The big difference though is that the 262 is a jet, and would have an enormous speed advantage over the other fighters at all altitudes. In contrast, the Tempest is a prop plane like the Dora and G10, and has a small speed advatage at low level, and is slower at medium and high alts. The Tempest would fit much better unperked than the 262.
The contemporary of the 262 would be the Meteor III.
As it stands, only 2 prop planes from 1944 seem to be considered for perking, the Tempest and Spit XIV, the 2 RAF fighters from 1944. Can you imagine the wine if the only 2 prop planes perked were the Dora and G10?
I think the Typhoon role rate is deliberately too high as a play balance, because the RAF doesn't have it's proper 1944 planes.
