A Bank PO salary and SSC recruit gets an almost similar salary. However, a bank employee has more switching options rather than a SSC recruit.
In IBPS PO you might get sent in rural areas or the best cities. You may also get job in your home town. In SSC CGL the occurrence of transfers is less and the employee might feel stuck.

In SSC the growth is relatively slow unlike Bank PO, the growth is usually fast track if you are open to new opportunities.
