TU Braunschweig vs FH Aachen (Masters Aerospace)

I have received the admission letter in TU Braunschweig's Masters in Aerospace Engineering course and FH Aachen with masters in the same area. I am really unable to choose between the 2 and want to inquire about the same to someone who has already studied in TU Braunschweig. Can anyone help me with the same? #masters
