Dear aspirant,

This is a very subjective question. Power is relative, with respect to others and within an organization. To give you an example, An IAS of some big district like Moradabad have more power than the IAS in some small backward district. But this does not belittle the profession of IAS.

Similarly, an ISRO engineer/scientist working on Chandrayaan will have more salary then the engineer who has just entered the organization and working on some existing common project.

Therefore, both of them are relative to the work you do, where you're at, your experience, etc.

Hope this helps. Thank you.
