Captured King Tiger - worth getting Twitch Prime?

Falathi: The tank itself is pretty decent. You have reasonable gun stats, decent armor and not a bad speed for a heavy tank. 
There are cons - you need to position yourself properly to bounce enemy shells. The alpha of the gun is rather small, so you can`t trade shots - it`s more like Tiger I. Top speed is nice - but the specific power means it takes time to reach it, and the vehicle doesn`t turn that super fast. 
Still, it`s pretty solid for its tier.
