I am currently seeking reference letters from professors for my masters application. It struck me that the professors that I'm close with, who know me on a more personal level (through projects, work, etc.) are not as academically renowned as some other professors who may only know me as one of the many students who got an A in their course.
I would like to know how their reference letters fare when used to apply for masters in prestigious universities. Is a more personal reference letter better, or a letter written by a more well known professor?
