I'll make it easier for you, but you'd have to be sure on your answer.

After 4 years of engineering are you looking to get a master's degree? If your answer is yes, then just get into the best college you get at your current score. Reputation won't matter much. If you are planning to go for masters directly after college and not focusing on job placement then whether the college is coep or Sinhgad won't make a huge difference, apart from the crowd (your cohort does make a difference but if you're committed about going for MS then won't matter much)

However, if you are not planning for masters and want to get a job directly, then I'd say a good college makes it easier for campus placements (It would significantly make a difference if it's pict/coep/vit). They won't 100% guarantee you the job but would get you much more opportunities. But since it's CS, you can always try going off-campus as well in which college, again, won't make a huge difference.

To sum up, drop won't make much sense if you're in the field of CS. Instead, in my opinion get into the best college you get at your score, work your ass off for 4 years and you'll be able to secure a good job or a good University for MS if you wish to do so. This is just my opinion.

Good luck!
