According to my friends at DAIICT, it is definitely a better choice among the two. Considering factors like placement, brand reputation, and coding culture. 

The points below give a brief overview of some of the advantages of choosing DAIICT over SVNIT.

• According to some professors of SVNIT itself, DAIICT is a better institute for CSE and IT, compared to SVNIT.
• The overall placement statistics of DAIICT are far better than that in SVNIT, with more high-paying jobs offered in the institute. 
• DAIICT doesn’t have as good a reputation as NITs in India. But, in companies like Amazon, MAQ, Morgan Stanley, etc, DAIICT has a far better reputation than SVNIT.
• There is an excellent open-source coding environment in DAIICT. 
• The number of GSoC entries from both institutes makes it evident that DAIICT has much more success in open-source contribution.

Therefore, it is clear that DAIICT is a much better choice, especially in subjects like CS and IT. In DAIICT, there is a high exposure in higher studies among students. There is a good environment for competitive coding too in DAIICT. In every notable coding contest from platforms like Codeforces, Codechef, etc, there are at least 30-40 participants from DAIICT.

Unlike other NIT campuses, the SVNIT campus is located in the main city. Other NITs are generally located on the outskirts of the main cities. Here are some details about SVNIT.

• Any basic requirement that concerns your stationary or entertainment can promptly be fulfilled as everything is covered within 2 kilometers of radius. 
• The campus will never disappoint you as, like any other IIT/NIT, the SVNIT campus is adorned with greenery all around
• Previously, the lake present near the campus used to be a part of the campus too, but now the authorities have constructed a wall dividing the lake and the campus. 
• There are no bus or shuttle services inside the campus as it is relatively smaller. But the roads are pretty decent. Several people come inside the campus for morning walks.
• New CRC buildings are where classes are conducted for the first years. The infrastructure is excellent. 
• Old classes carry on in the old departments as it is. 
• Old and new hostels are present on the campus. Third and fourth-year students stay in the new hostels.

• A ground is present on the campus too where students prefer to play cricket and football. But since it is not maintained that often. Also, two basketball and tennis courts are present on the campus. 
• As far as indoor games are concerned, there are two table tennis and badminton courts. A gym is also present, but it is restricted for the first years. 
• Staff bungalows are appealing. Behind that, there is the girl's hostel.
• For financial services, there is a post-office and SBI branch present on the campus too. 

This should give you an idea about the SVNIT campus. You can find the photos of the campus on the official website.

My friend stayed at Mother Teresa Bhavna and here is her input regarding the mess menu.

Breakfast menu:

• In Breakfast, they serve Poha, Maggie, Pasta, Bhel, Idli sambhar, Bada sambhar, Dhokla, Sandwiches, Omelets, Paratha, Upma, Veg Frankie, Uttapam, Boiled eggs, Dosa.
• Apart from these, there are few other options for breakfast like Bread(brown and white), toasted and not toasted with jam, sauce, and butter. You can also have cereals, with milk. These options are available every day.

• On alternate days, they also serve Dahi vadas, chili pakora, and Dahi chaat.
• The Saturday lunch is always special with paneer, sweets and ice cream.

Dinner menu:

In dinner, they serve parathas, pav bhaji, cottage cheese, Manchurian noodles, potato, along with jowar roti, dal dhokli, and egg curry.

These are the mess menu of SVNIT, Surat. Anyways it changes but I am mentioning the food items which are more constant in the menu.

SVNIT is theoretical research-based while CEPT is more practice-oriented. If you are interested in pursuing a Ph.D. further or if you would like to get placed on-campus, then SVNIT is your place.

After matching your requirements focus on excelling at GATE to get structural engineering getting into structural engineering at SVNIT.

If you choose CEPT then you will have to work hard to get a job. It is well known in all of Asia and has one of the best civil engineers. The faculty is highly qualified, its alumni are working in MNCs and most of them get annual trips abroad.

Lastly, if you are not from Ahmedabad you will have to stay at the CEPT hostel which is an awesome place to stay, as you will see for yourself if you so choose to be.

Be mindful of the fees because both SVNIT and Nirma charge more about the quality they provide.
