The 152 pretty much has to be flown with the BnZ style of fighting. This means it really has to be flown holding as much E as it can. Id consider it an E plane at any alt because it simply cannot perform well without it. It has a great lift ability to rope planes and get up higher using its conserved E. Compared to the P47, it zoom climbs and builds up E more quickly after a manuever. I feel as though it can rope a 47 given the E and situation in a vertical zoom climb. If the P47 gets slower than the 152, the 152 can use its conservative E to get over the top of the 47.
When you look at the 152 compared to the F4U, the 152 has to be able to escape from most planes with its speed and E, or out climb them or else it's pretty much dead meat. The F4U is much more versatile in the fight, but when you are talking about conserving E and utilizing it, the F4U actually doesn't hold it that well. I mean it's better than a lot of planes. But when you get slow with it, it's difficult to gain speed quickly, it doesn't really build up quick speed/ E like the 152 190D or la7 is capable of. If you are fighting low and slow on the deck against a BnZer in a F4u. You are going to have a hard time because it doesn't build up E well enough in some cases to make a good counter punch shot on the overshoot. The F4U and 47 also tend to get slow if you don't fly it in the BnZ style and it's difficult to build up speed. You tend to lose speed getting a shot while the Ta152 would fly off and regain it and try another pass. It doesn't regain its alt after a dive as well as the 152 or reagin the speed as quickly. I think when it comes to planes that can hold E well it really depends on how quickly they can accelerate, there ability to lift up and away with a strong engine where most planes wouldn't be able to pull up, and the ability to zoom climb better than most. The p38, 152, 190D, P51, and K4, are the types of planes I'm thinking about.
