The La-7, Hawker Tempest, F4U-4, and the Spit14.. they are all comparable planes. All of them boasting incredible performance as a late war fighter.
 ...
 But let's think about it this way.
 The La-7 is severely ridiculed in the MA. As a free plane, so many people fly it in such a blind manner that they are not even considered a serious threat anymore.
 They are the living symbols of "stupid n00b flying". You see actually more veterans concerned about fighting a '42 Spit9, than the '45 3x20mm La-7. 
 The La-7 maneuvers better than the Tempest. The Tempest has better jabo capabilities and better firepower, but it's not such a great plane at high altitudes, either. The Tempest has a delicate inline engine with high probability of coolant problems when engine hit. The two planes both have the same exceptional quality of low alt speed and acceleration. 
 So, -10 perks for the relatively weaker firepower, -10 points for the lack of jabo capabilities, and it would be worth 50 perks as a pure fighter plane comparable with the Temp. Okay, okay, -30 perks for being not a rare plane - that still makes the La-7 worth about 20 points. 
 So, anybody here willing to fly a La-7 at 20 perks?
 Anyone?
 I didn't think so. 
 ...
 Okay, how about a simular comparison with the Bf109G-10 and the Spit14? One's a free plane, the other's super expensive at 60 perks. 
 The Spit14 was not a rare bird. Simular speed and climb performance compared to the G-10. More effective firepower, but like the Bf109, short legged in ranges and not much jabo capabilities. 
 So, -15 points for worse maneuverability. 
 Anybody wanna fly the G-10 at 45 perks?
 ...
 Okay, sorry, my point is this. 
 The Tempest, F4U-4, Ta152H, Spit14, these four planes are all too severely overperked. 
 10 points for the Temp, 4hog and the Ta
 5 points for the Spit14. 
 My suggestion.
