Without any second thoughts, IIIT Lucknow is a fairly better choice than NIT Delhi in terms of infrastructure, coding culture, and placements. Let us consider these criteria individually.

• Infrastructure: NIT Delhi is quite far from the hostels so the commute time is high whereas IIIT Lucknow campus and hostels are in close proximity to each other. It hardly takes 5 minutes to reach the campus from your hostel room. Thus saves time. 
• Coding Culture: IIIT Lucknow has a more extensive coding culture than NIT Delhi. Recently, a team of students from IIIT Lucknow secured 9th position in ACM ICPC regionals. The performance of the recent batches is also testimony to the excellent coding culture.
• Placements: IIIT Lucknow is definitely better in this aspect too given that last year its higher package stood at INR 59 LPA. 

Overall, IIIT Lucknow is easily the better choice than NIT Delhi considering all major aspects.

You need to consider several factors before deciding the best college for yourself. Here are a few factors and the preferred choice if you give preference to that factor alone

1. Alumni : The age of the institute determines how strong the alumni network is which is very crucial for the development of the institute. In terms of the alumni network the preference order should be NIT Jaipur=NIT Kurukshetra> NIT Delhi
2. Placements: The placement scenario is somewhat similar in all the aforementioned institutes. However, NIT Delhi has a slight advantage being in Delhi. The order should be NIT Delhi > NIT Jaipur = NIT Kurukshetra
3. Faculty: In my opinion, NIT Delhi has the best professors.
4. Campus : NIT Kurukshetra and NIT Jaipur have equally beautiful campuses whereas the permanent campus of NIT Delhi is under construction.

Ultimately, the final decision depends on your personal preferences.

PEC Chandigarh is better than NIT Delhi. It offers better placements. PEC Chandigarh placements 2021 had witnessed the highest CTC of INR 42 LPA. The average CTC received by the students was INR 10.83 LPA. More than 123 companies visited the placement drive. Exxon Mobile, Google, Airtel, Microsoft, etc. were some of the major recruiters that took part in the placement drive. 

Located at the heart of Chandigarh city PEC also offers a better campus life. 

I would recommend you go for CSE from better NITs or other institutes like PEC, IIIT, YMCA, and others. Even IIIT Delhi is a decent option if you are considering staying in Delhi only. The reason I am against NIT Delhi so strongly is because it’s new and its CSE course is yet to develop and reach a certain standard. It does have its own campus and the facilities are also very limited here.

• There are serious connectivity issues as the hostel buildings are very far from the main campus. The accommodation facilities are poor and not at par with NIT standards. 
• Being newly established it has a very poor placement scenario not comparable to the old NITs or other institutions like PEC Chandigarh, IIITs, etc.
• NIT Delhi does not have an active coding culture. The timetable is very rigid and the classes are conducted consequently without many breaks.
• The faculty is also underqualified and has only a few good professors. 

Ultimately, I will suggest that if you are seriously inclined towards CS, and are ready to explore endless opportunities in the same,  then consider joining some other NIT than Raipur or Delhi. Go for IIIT Delhi instead!

Choosing the right college for your undergraduate studies is an important decision and depends on several factors such as your academic interests, location, career goals, financial situation, campus culture, and more.
