you can analize with the placements and rest ihm institute s are following same standards and criteria of syllabus in all colleges

All these universities are equally good so it depends which branch of engineering you are going to opt for. Like for CSE I would suggest you to go for Lovely Professional University reason being good academics and placement record. And if you want good scholarship also then go for Chandigarh University, Lovely Professional University, JNU etc.

I also doing the same from cu this year

If you are interested in Engineering then I would recommend you to go for universities like JNU, Lovely Professional University, Anna University, Chandigarh University etc. But now it depends in which branch you want to pursue B.Tech like for CSE Lovely Professional University will be the good option.
