The more detailed one, read below.
Cost in gold:
Löwe - 12500
Type59 - 7500
Statistics taken from by battles
Löwe
- battles: 409
- total damage done: 672148
- avg dmg/battle: 1,643.39
- battles: 489
- total damage done: 710313
- avg dmg/battle: 1452.58
Let's calculate the total shell costs:
Löwe
- shells fired: 3594
- total cost: 3701820 Cr
- shells fired: 5799
- total cost: 1461348 Cr
Also taken from my battle statistics, showing something interesting: although I have more battles with T59, I have more total time played with Lowe. Wasted time spent in Battle .. no doubt!
Bottom line is that Löwe cost a lot more gold than Type59, has a greater shell cost, is a lot slower (comparing it with the other heavy tanks in it's tier).
Note: There is one negative aspect of the Type59 I forgot to mention .. since there is no chinese tech tree, training the crew of this tanks is absolutely useless. I do hope in the future will have such a tech tree.
At least, you can re-train the Lowe crew to any other german tank you want.
