This is a personal decision but I think it’s better to be pragmatic about it. If your country of origin permits dual citizenship I’d do the naturalization simply because it gives you more flexibility. It’s a more secure status, no need to worry about renewing or spending longer periods abroad. And you get to vote of course.

Citizenships and passports are bureaucracy and they don’t define who you are, that comes from your heart. I’d look at it as a practical matter.

My understanding is that Germany is looking to start permitting dual citizenship later this year.
