I have spoken to graduates of almost all Universities of Russia, Ukraine, Phillipines , Kyrgyzstan, Kazakhstan.
Standard of education is almost similar i.e. Good. Teacher are good everywhere as they all are doctors and surgeons already.
China is best option (45MCI listed University ) as they provide scholarship , great infrastructure and world ranked university but seats are limited (60–100) and you need to have good score in NEET and board exams.
