Hi,

CBSE is central board of our country which is common for whole country. While Rajasthan state board is particularly only for Rajasthan. I feel that CBSE board will be a better choice as it is more recognized than any state board. Along with it, if you prepare for Civil services or any other exams, you need to follow ncerts. NCERTs are the prime books in CBSE board. So, CBSE would be a better choice.
