Both of the colleges you have mentioned are good. But if you want to compare them then you have to consider different parameters that will help you to enlighten your career prospects. Now as per the online reviews available, depending on the parameter of Faculty, Placement, Infrastructure and Curriculum Lexicon MILE is better than Sinhagad School of Business Studies.

This is my prospects but I would recommend you to conduct a research by yourself and then only conclude your argument.

I hope this answer helps. All the very best for your future endeavors!
