That's pretty right, except that the Jug and the Corsair were never good dogfighters neighter, but they were perfect for boom'n'zoom. Yeah, inline engines were lighter and more aerodynamical, but as you stated, they were more complexe than the radial ones, wich can sometime come back with one cylender or two shooted up. Think about the Napier Sabre from the Tempest and the Typhoon, those were mechanical horrors, with a very small life time, and with a real tendance to break for god knows what...
But yeah, for ground pounding, prefer a good radial engine! Think about the Jug and the Skyraider!
