Keller is part of Devry, and a lot of employers do not respect Devry degrees.
In general, if you can get into an AACSB accredited MBA program, you want to go to an AACSB accredited program. A lot of employers will not hire MBAs if their program was not AACSB accredited. I'll link you to the website so you can look up all the accredited programs in your area:

For some employers, in addition to the fact that the MBA must be AACSB accredited, the reputation of where you get your MBA also matters. So while, for example, it's not necessary, for most employers, that you get your MBA from Harvard; if you were choosing between Fordham and Montclair State, you'd want to pick Fordham.
