Hey Alok. I have one. Benefits are listed on the device page on Amazon - but happy to answer any questions that you have.
I moved from a very old Kindle PaperWhite which I used for 4+ years - so it was a big jump for me.
My main reason for getting the Oasis were the physical buttons, the higher resolution screen and the warm colours. All good and work as expected with better ergonomics as well. So I'd recommend.
