My take on NUS and Nanyang Universities
My take only and only on the school. Most of it applies to NUS, too. Of course, research matters, but let's assume research-wise things are quite good.
Nanyang is a great school, though I wouldn't look at the ranking (ranking engineering, indeed, is a thing). However, their infrastructure is pretty awesome, which again is a reason for ranking to be good.
Regarding the catering, tons and tons of different food is available to you to take every single meal on campus. This should not be taken for granted, because it's not only quite affordable but its quality is also decent. And yes, food diversity is so high. These are all on campus, so if you want to go off campus, it's important to note that it's going to be a 40-minute train ride to the fun part of the city.
There are so many sports facilities that you can't decide which one to go to, and they aren't usually congested.
Office spaces are quite nice and tidy (although it depends on how you take care of it). Plus, a lot of study spaces in the buildings. No need to argue with your lab mates to stay low volume during your Zoom calls or desperately walk around the building to find a proper place to start a call. It's also super cold inside. Ironically, you need a jacket with you in Singapore :)
The offers are pretty generous, and you can live comfortably if you want to live only off of that. Things related to travel grants, etc., are no concern basically. At least, I remember the SINGA or NUS scholarship covered literally EVERYTHING. There were also some one-off travel assistance payments to help settle in Singapore.
This is problematic when funding does not automatically secure these extra expenses. E.g., UK studentships usually do not include conference attendance bursaries or introduce some high hidden costs like IHS charges, etc. The worst part is that later, you realize you need private health insurance. I felt sad when I had to pay for IHS at the time. No one told me (maybe I didn't do proper research)! By then, it is so late (VISA process) that you have already declined other offers.
Yet, I believe the graduate school needs to be more diversified (though I haven't looked at the actual numbers), but with eyeballing, you may tell the very low number of people from South American countries or African nationals. F-world country nationals are there too, but very limited, at least in the graduate program. This impacts your experience a bit compared to a place like London.
