Galgotias College of Engineering and Technology is obviously better than ABES Engineering College. It should not be confused with the Galgotias University as it is different from this college.

Galgotias College edges past ABES Engineering College in almost every aspect; quality of infrastructure, teaching methodology and faculty, and most importantly placements.

• Looking at the placement record for 2019-20, Galgotias College of Engineering and Technology had the highest CTC and average CTC of INR 11,18,669 per annum and INR 3,86,000 per annum respectively 
• ABES Engineering College had the highest CTC of INR 10 LPA.
• They both are close in case of the locality as well; ABES Engineering College is in Ghaziabad while Galgotias College of Engineering and Technology is in Greater Noida.
• Both have equally competent faculty, placements, and facilities

So, as we can see there is not much of a difference, in reality, to sway in favor of one over the other. Any college you choose will be equally good for you. More important is your performance in the college to land a top job otherwise no college can give you anything readymade.
