Yes, accounting/tax related stuff is still annoying. But there are a few more advantages:
* Employee share options are taxed when they sell the shares, not when issuing the option (regardless of strike price) nor when exercising it.
* Changes to the shareholder structure (e.g. raising capital) don't require visiting a notary
And I'm not sure if incorporating in a different EU country (while still looking just like a German EU Inc) would avoid some of the German pain points.
