Jaypee Institute of Information Technology

There's a little correction I wish to make to your question, it is actually JIIT, Noida Sector 62.
Going towards the answer of your question,
I feel that with 73 marks in JEE Mains you might have secured around 1 lakh JEE mains rank, which can easily land you in JIIT Noida-62, but you won't be able to get a seat in computer science engineering or information technology, which are considered more demanding in the college but you'll be able to get a seat in electronics and communication engineering which is equally good w.r.t academics. Also, we have amazing faculty in JIIT Noida-128, wherein you might get computer science engineering as well as electronics and communication engineering.
So feel free to apply for the admissions.

Engineering at Chandigarh University is setting a benchmark every year that is on a subtle higher inclination. Practical teaching and learning methodology, Research oriented studies, placements from Top Notch Multinational companies and excellence centers of globally reputed firms makes Chandigarh University a stand out choice among the ones who want to give their career a free flowing and a satisfying start. It is the only university to have lodged more than 200 partnerships with foreign universities which are well reputed and are within top QS rankings. The highest package offered to the students last year at Chandigarh University was 31.7 lac. More than 450 companies including global IT giant such as Google, Microsoft, Deloitte etc. , and other renowned firms such as Amazon, Wipro, Haier, HP etc. Are frequent recruiters here. Chandigarh University believes in developing students completely and not just academically and this is why the Alumni here speak tons in praises of this institute. Mechanical Engineering here has also seen growth with companies like John Deere, Eicher etc. Being the top recruiters. Talking specifically about CSE placements, the highest package offered here was 31.77 lacs in the recent placement session which was offered by Amazon and the average package offered to the students was 4.5 lacs. Chandigarh University is the most trusted and sought after education institutes in the region and without any doubt has the highest return on investment which is a defining factor when you decide to invest 4 years of your life in Engineering. CU has a industry oriented teaching learning process for its students so that they do not lag behind in any aspect of inheriting technology and there is no doubt that Chandigarh University is the best when it comes to placement. To get to know about Chandigarh University and comes a step close to deciding your bright future, you can also go to http://www.cuchd.in. Personally speaking, I would like to rank them as follows:
1. Chandigarh University
2. JIIT
3. Manav Rachna.

I did a bit of homework for this question. See my friend, JIIT-Noida can offer you an average package of around 4 LPA- 5 LPA and also 100% placement.
Average Package - 3.5/5 Placements - 4.5/5
SNU as per stats, there is no such information available on the average package offered to students but jobs are offered to only 60% of student every year.
Average Package - NA
Placements - 3/5
USICT offers its students average package of around 6 LPA with a good placements stats as well.
Average Package - 4/5
Placements - 4.5/5
Chandigarh University offers an average package around 5 LPA to its students with 90-95% students getting placed each year.
Average Package - 3.5/5
Placements - 4/5.

First and the foremost thing, if you have a JEE Mains rank wherein you can get any government college, go for that.
Next, let's come to the topic of JIIT, Noida:
JIIT has two campuses in Noida i.e. Sec-62 and Sec-128, wherein Sec-62 is considered better in terms of faculty, placements and overall stats.
So, is JIIT worthy of 12 lacs?
If you are planning for a private college, then I will recommend that JIIT is good for you. Spending same or more amount and taking admission in colleges like Amity, Sharda, etc., is no use.
JIIT offers a good campus (a bit small), decent infrastructure, decent faculty, good hostel facilities, a very nicely structured curriculum and yes, secured placement.
If you have fancy dreams about your college, then JIIT is not for you.
JIIT has a good name in Delhi/NCR. According to me, it's a good choice for those who have secured around 50K-60K rank in JEE Mains and are looking for a private college.
Spending 12 Lacs is heavy, but you'll be at a good place.
