All the 3 NITs namely NIT Trichy, Surathkal, and Warangal are considered to be among the top NITs and are highly regarded engineering colleges. Their rankings are also quite similar but in my opinion, the preference order should be 

NIT Warangal>NIT Surathkal>NIT Trichy

The reason Trichy should be your last option is because it does not permit students to go for Internship which in turn results in no PPOs. Many students get PPOs and thus are free from the stress of sitting for placements. Also, internships give you a better experience of the real world. Here is a brief overview of these 3 colleges

The placement scenario of these NITs is somewhat the same so that should not be your primary concern. Focus on personal preferences like proximity to home, hostel fcilties, etc

I have friends in all the 3 institutes so I happen to be the right person to answer your question 

A friend in NIT Trichy told me that the lectures are boring and the professors are incapable of delivering the concepts in a skillful manner. Most of them are hardly interested in teaching and offer no individual assistance. Only a few exceptional professors help you here. 

Meanwhile, my friends at BITS Pilani and IIT Bombay were all praised for their respective institutes. 

• These institutes offer better job opportunities and exposure in the form of scholarships and internships.
• The research culture at these institutes is yet another reason to prefer them over NIT Trichy.
• The crowd quality of these institutes cannot be compared to the crowd at NIT Trichy. IIT Bombay is the best IIT and attracts the highest JEE rankers while BITS Pilani with its no-reservation policy only accepts the cream crowd.
• These institutes provide a path for their students to inculcate and harness their talents. NIT Trichy fails to realize the potential of its students and only focuses on theoretical learning. 

So yes there is a huge difference in the quality of education and opportunities offered by the aforementioned institutes. However, in the long run, it’s your skills and talents that matter. 

The choice of the institute for pursuing an MTech in Electrical Engineering depends on what you want from your Masters. 

• For those on the lookout for placements, NIT Trichy has a good placement scenario, especially for Electrical Engineering. They are even better than some well-known IITs in M.Tech, especially Power Systems. 
• However, if you are willing to pursue a career in research after MTech (Ph.D.) then you will have to give great importance to the choice of the institute. An IIT is best suitable for prospective Ph.D. holders as they have global recognition too.

Ultimately, the better institute is a matter of preferences and career prospects.

My uncle is a successful architect and has the experience of employing many architects. He shared his experience stating that architecture students of both BIT Mesra and NIT Trichy are Unfortunately both the institutions are engineering colleges where architecture is considered equal because both are engineering colleges with Architecture as just one of the many specializations offered by the institute. None of these institutes are specialized in this field so the students study in a more engineering-oriented ambiance. They lack the ability to think independently of constraints imposed by engineering abilities available in India. I recommend you pursue Architecture from an institution that has Architecture as its flagship course like CEPT or SPA.

Nevertheless, comparing Architecture from BIT Mesra and NIT Trichy, I will say the former has a better crowd and opportunities than the latter. Both are somewhat at similar levels and it's hard to make a direct comparison. It's that students from BITS Mesra are better exposed so they make better Architects than NIT Trichy students.

NIT Surathkal has better placements for MTech. According to the recent placement highlights, the highest CTC and average CTC offered were INR 28 LPA and INR 12.25 LPA, respectively. Companies such as L&T Infotech, Standard Chartered Bank, ZS Associates, Capgemini, Tredence Analytics, Exl Service, etc. are the major recruiters that take part in NIT Surathkal placements. 

NIT Trichy is the better option. It is better than SSN Chennai in terms of academics, infrastructure, peer group, and campus life. The student crowd of NITT is amazing. You will share your lectures with talented students and get to learn from them. It has a good placement record as well. According to NIT Trichy placements 2022, the average CTC received by the students was INR 6.5 LPA.

Although as a branch ECE is more preferred by students, given a chance you should choose NIT Trichy.

Between these two options, NIT Trichy is definitely better. Here are the reasons why.

• For the last several years, NIT Trichy is the best NIT in the country. It is consistently ranked among the top engineering colleges in the country. NIRF 2021 has ranked the institutes 9th for B.Tech. 
• The 5 old IITs and BITS Pilani are the only institutes that are ranked above NIT Trichy.
• NIT Trichy requires the highest cutoff in JEE Mains. 
• According to the NIT Trichy placement report of 2020, the average CTC offered to students is INR 6.5 LPA. While the highest CTC offered is INR 42 LPA. 

According to teaching, infrastructure, facilities, and campus life, NIT Trichy is definitely better than VIT.
