voted for TE37. just because i had both wheels before and i bent 2 out of 4 advan RS rims before and had to get one fixed and the other completely replaced... they just arent that strong. no issues with the TE37 at all..
HOWEVER, take it with a grain of salt because my advan RS rims were 19inch and TE37SL were 18inch. so the size difference definitely helps a lot.
