Brandeis will be less selective and a bit smaller. Still very selective.
A lot really depends on your academics - where can you get into. And budget - Tufts for example has no merit scholarships. Others mentioned do. Tufts is $90k a year and growing and while they do meet need, the far majority of students are full pay.
Both Tufts and Union, for example, offer engineering - but now that you said your majors - most any school will work for Econ and soc.
Lots of schools within, say 150 miles of Boston - including Smith and Mt Holyoke since you mentioned women’s schools.
Maybe not the same vibe as Tufts but you have to decide what is important. If it’s Boston, you can google a list of nearby schools.
Not Boston focused but here’s an old thread.
