CS-53 tier 8 and CS-63 tier 10

churchill50: In my opinion, definitely the CS-63. The CS-53 has good pen and a decent alpha/pen mix. But the gun is quite derpy. It also takes quite a while to reach its top speed, has virtually no armor, and only has 1,300 HP. It's not that good a tank.Plus, the CS-52 LIS is miles better. The CS-63 on the other hand is rather solid. Sort of a different flavor of Leopard I that trades some gun reliability for insane mobility and good DPM. It's quite solid in pubs, and is also used a lot in Clan Wars.
