Sbi(State Bank Of India) is the oldest bank of India.Till that time they have grown their services over a large area.They provide a good experience of banking.Till then its customer has also grown in large numbers and due to this their bank branches are mostly crowded.This sometimes creates some inconvenience.The advantage of is is that it also have coverage in every village of India which other banks not have.Their ways of working are same as other banks.I would only suggest you to open an account in sbi if you live in a village or a remote area where no other bank gives their coverage.If you live in a city then there are better options than this and as I always say the end choice is yours!
