Hey !

As you are preferencing a college better in academics , then you should definitely go for SAIMS ,indore . The faculty of both the colleges us good and experienced , but the difference is thaf in SAIMS , indore , faculty gives their best for their students while in RD GARDI college , nobody focuses on the studies in college as they teach everything in their coachings. So , for good knowledge , you have to join their coachings as well. Placements are better in RD GARDI , UJJAIN . Also , it is strictly disciplined . Both the colleges promise equally if we come to focus on labs , but RD GARDI UJJAIN  , fails to fulfil their promises in some cases. And SAIMS , INDORE has  well managed labs and they focus equally on practical knowledge as theoretical knowledge.

Well , you can also compare both the colleges using the following link :
