If you know any better th7 farming bases feel free to post them.

I prefer the second. But they are both pefect.

But maybe its their weakness also. They are predictable.

Of the two you posted, one is a farming base and the other is a trophy base. They are meant for completely different situations. Deciding the better of the two is wholly dependent upon the intent of the user. Since you are asking about better farming bases, I assume you will prefer the one with the TH outside.
