"1 Year Accelerated MBA" VS "2 Years Traditional MBA" in US?

Please Help Me in figuring out does 1 year full time Accelerated has any negative impact on placements? If Yes please explain how?

Have researched on both and find out and found the main differences & drawbacks for both was : 

1 year Full time MBA : Intern-ship & less courses

2 year Full time MBA : Cost & Time

Would 1 Yr MBA be an optimized choice over the 2 YR MBA in USA? why ?
