It is not always like the govt. colleges are the best. It depends upon your interest that in which course you want to go with. It may be possible that in private colleges the BDS or any other course than MBBS is good but at the same time in the govt. college MBBS is the better. But If you want to go for MBBS only then you have to look for the colleges and at the last you will get the govt. college only on the basis of your merit rank. If you are not eligible to get the govt. college in MBBS then you can try private college also. Some private colleges are the best in India. So it is not like that the govt. colleges are only the best. So you can go for the private college if you have no financial issues otherwise it is completely fine to go for the private as well as govt. college with the choice of your course.
