What is the best way ? Has anyone used Uber in Germany ?
Read this information about individual and group tickets and you decide. https://www.mvv-muenchen.de/en/service/mobility-services/air-travellers/index.html It’s quite easy to use the S1 or S8 to get into the city center. Know which stop your hotel is closest to. On the Rome2Rio site it lists Uber as about 70-80€ for the 29 mile trip.
Look on the airport's own website (every airport has a transportation section on its website with all alternatives). There are several easy and efficient public transportation options into the center. Germany really excels at public transit, I would give it a try.

Or take a taxi, they are allowed to use bus lanes, others not.
I inquired about the airport to the main train station in Munich and had some extremely helpful responses. If you can find that thread it may help you as well.
The S-bahn train is an easy option, and one of the cheapest. You can walk out of the airport terminal, walk down some stairs to the S-bahn station and buy a ticket from a machine with a credit card. S1 and S8 both go to the city center and main train station via different routes. Departures about every 10 minutes. The Airport-City-Day ticket is about 13 euros. The ride is about 45-50 minutes.
