After IIT Hyderabad and BITS, Thapar University is the third-best private college, while the other two are unsuitable for engineering.
If you have the option, choose a branch in Thapar over SNU.
Thapar University is one of India's most prominent and best engineering institutes, ranked second only to Bits Pilani in terms of private institutes. In the NIRF rankings, Thapar Institute of Engineering and Technology is holding 20th position.
