Your question is one of those that is basically subjective. You will be living with them, not us, so it is very difficult to advise you, beyond the usual of taking your time, listening to both with music with which you are familiar, and realizing that it is likely that whatever you select, something else will be better in some way or other. At the level of speaker you are considering, I would probably go with
