NSLI-Y vs NDLS - Decision

For my daughter:

She was wondering which one of the two to choose (as she was accepted to both) and which one specifically would be better for college applications. She’s rather indifferent about going to either and is stuck between NSLI-Y (lengthier program, and thus more experience to talk about when developing essays) and developing other ECs during the summer with NDLS (10 days, much more time over the summer).

Would really appreciate any help. Thank you!
