Mesivta Ateres Yaakov (formerly of South Shore Yeshiva) is also a good school. It is entirely dependent on what you are looking for. Some of the schools are more intense in their Talmudic studies, others give reasonably nearly equal time to secular classes. And others are extremely strong in the secular department, as well as very Tziyoni.
I know HAFTR boys who became real masmidim, and I know Darchei boys who did not. There are so many factors involved. You should attend all the Open House meetings for the Yeshivos and see what appeals to you. Then speak to other parents in your son’s Yeshivah and try to get some more specific feedback.
