I still find it to be lesser "evil" than schufa - which, I'm pretty sure, is also extremely discriminatory towards people who move to Germany and giving them worse score by default. Hopefully you'll get enough optional data to be able to prove that too.
But when I moved to Germany, I was under the impression that potential landlords just want to make sure you don't have negative entries, and didn't care much for the actual score. Luckily I managed to find an apartment belonging to a Russian investor, who didn't ask for my record at all. In the end I never got myself to even request a free report.
However if you try to get a phone contract, credit card, internet contract, or anything else that requires payment in the future then your score is pretty much the only relevant part.
And that score is (maybe it varies by country) completely abysmal by default if you've moved to Germany - and it improves very slowly (<1%/yr).
As for credit cards, that's pretty common, traditional banks want to see your salary landing on your checking account for a few months before they issue you a credit card. Comdirect gave me a prepaid VISA in the meantime.
Anyway I ended up using a debit card (the MasterCard from N26) for almost everything, and later on I got a Gold credit card from Advanzia (I believe they do get information from the Schufa, but you also start with a pretty low monthly limit and need to prove them you pay your bills before they raise it).
It's worth watching. They show how they where able to take over accounts and such.
