It doesn't really matter.

If you do business in Germany you are evading taxes just by the fact of doing business. Everything and anything you make belongs to the government. It is an unfortunate loophole in the law that temporarily permits you to steal some of your profit back from the government where it rightfully belongs.

Yeah, this is sarcasm, but not really. The practical reality is that it simply makes no sense to incorporate in Germany. For example, the OP missed six months of opportunity just to please the bureaucracy and it's not even the end of it.

What if there were multiple (2+) founders of a company, and some lived in Estonia? I think in one case they had a Croatian co-founder as well.
