Assistant Manager SPD vs Manager MLC
 

I need suggestions regarding the following posts at Ministry of Defence:
Assistant Manager at SPD (SPS-8)
Manager IT at Military Lands & Cantts (BS-17)
Assistant Manager at POF (BS-17)

Which one among the above three organizations is the best with respect to job environment, perks and privileges and future promotions? If a person has a chance to join the above three organizations, which one should he go for? Honest suggestions will be appreciated. Thank you
