On the other hand sri sairam college is also not bad.

Above link is for sri sairam engineering college. According to my observation rajalaksmi college of engineering would be the best choice.
Now it is on you.
Hope it helps
All the best!

Dear Saran, I get some feedback of some recent students of both colleges and I also read some comments over the internet and all of these compilation results Rajalakshmi college of engineering is better than Sri Sairam because of teaching and faculty and placement but have some cons in facilities.

All the best
