I guess it depends. Setting up a business in Germany might be easier (haven't done it so I don't know, but there's a good startup culture in Berlin so I guess it's possible), but as someone who has lived in Berlin I know there's a lot of pain and procedure to get set up as a resident, get a bank account, and so on.

As an example, to find somewhere to rent on your own, you need a German bank account to pay your rent with. To get a German bank account, you need to register as a resident with a specific address. Supposedly you need to do that within 14 days of entering the city, but when I last looked the wait to book an appointment online to register was a couple months.
