A PhD is a PhD, my dude. Even in Sri Lankan state universities, completing one is an absolute test of endurance. You need to publish at least four peer-reviewed papers, which is no joke.
The real issue lies entirely with resources. I’ve seen state universities running PhD programs without basic access to Elsevier or IEEE, and that’s just the start. Complete lack of proper lab equipment and zero access to the latest research makes it extremely difficult for students. They have to build and facilitate the entire infrastructure themselves. This is the fundamental reason why we suffers in university rankings.
I've seen a huge spike in PhDs in Gov campuses in the recent years. You hardly had any in past graduations, but now it's growing. With this I think underlying infra issues will get fixed eventually.
If you've ever done a PhD, you'll never ridicule one. (Well apart from Honorary ones

). At the end it's never about which University you've earned it. It's simply, how fellow scholars value your research and the impact it made
