I wanted to decide between these two for MBA, I've already received admit from University of Aberdeen but i found that it's not accredited still it is in world rankings like Guardian, Qs World Rankings, and coming to RGU it's accredited with AMBA AND AACSB, but it's not that much ranked, i will return to India post MBA, what i really want to know is which University is better in terms of education and career opportunities.

I hope you have a really compelling reason to go to Aberdeen. It's very cold and dark there, even compared to Edinburgh where I live. Neither of these are really world-class business schools.

RGU is the obvious choice in terms of MBA quality. It's a much better business school and a much better MBA.  Aberdeen Uni has a freshers' MBA with a much less experienced cohort. RGU is the leading MBA in the UK for energy, and has an international reputation in that niche. 

The generic, undergraduate-centred rankings are useful but when it comes to the MBA niche, many of the top European business schools are not well placed in those rankings of major universities (e.g ESMT, IESE, IMD, Insead, LBS, etc)
