Depends.
Advantages of doing your MBA from a good B-school:
1. You get a brand name that’s going to stick with you for the rest of your life.
2. You get to compete with and be friends with like minded talented people who are going to rock the industry in some or the other way.
3. You get to learn from some of the best professors around and if you are lucky, you will learn something that you can hold on for the rest of your life
4. You get a good job (most of the time) and your subsequent career progression can be fairly smooth.
5. People look at you as if you know a lot (may not be true) and with a good job and money in hand, things start becoming stable at a personal and professional level (can not be guaranteed)
