Both Ashutosh College and Vidyasagar College are reputed colleges under CU. Both have their own advantages. If you are only looking for quality education then choosing Vidyasagar College will be better for you. The only disadvantage here is the administration and they are not cooperative. 

On the other hand, Ashutosh will offer you better infrastructure. Academics at Aduthose are also decent. Both colleges will offer similar facilities. 

So, you can choose either of these two colleges according to your convenience.
