Hi Sauvik,
It's hard to compare, both TPR and Manhattan are quite popular. One way to find out is by visiting the centers and find out the statistics. Try to get in touch with ex and current students. Compare the study materials and the schedule, most importantly are the instructors certified? Diagnostic tests are important, enquire how realistic are the mock tests with the actual tests. Finally it's upto an individual how he deals with competitive tests no matter what. So choose the center as per your suitability.
Hope this helped. Please feel free to revert for any clarification.

Hi Mini, Princeton is the No.1 national university in USA and is recognized for its commitment towards teaching. One of the top 10 for Computer Science, getting into Princeton is not easy as it is one of the Ivy Leagues and candidates with exceptional grades and extra curricular are admitted.
Noteworthy to mention that famous personalities including Alan Turing, Alonzo Church and John von Neumann were among the residents at Princeton ( computer science department).
Hope you now have a feel of what is it like to study Computer Science at Princeton.
Good Luck.
