I like them for the most part. Almost always more readable to out things in the brackets rather than the .format at the end, and always better than the %. Occasionally I still use .format with really long strings though for readability.

GP said that f-strings were "the f***ing shit", not "f***ing shit", so I assume it was meant as a positive comment.

Not OP but I guess that's another colloquialism I shouldn't use around non-native speakers.

Correct, I am continually impressed with the versatility of eff strings. The-the is very important in that sentence.
