"Would " & " Used to ". They both are used for repeated action in the past tense. Then what is the difference between them?


I think the term "habits in the past" describes the use of "my grandmother would always say/ used to say..." better than repeated actions in the past. I think one can say "used to do" is clearer and preferred today, whereas "would do" has the patina of older and more literary language. I think "used to do" is preferred as "would" has already various uses.
