In the internet biz since 1993 here (retired): choose your registrar as carefully as your domain name.

Lowest price is the dumbest reason. It’s never the way to choose anything. ID what your needs are, what satisfies that, then shop for the best price…

Anyway at the moment for my purposes the EU with it’s gdpr and other rules is the best choice for many reasons. I’m using joker.com.

Top level domains (.ml etc) have their own rules, you gotta read them carefully. I don’t know anything about .ml and whether they allowed that usage or not.
