Perception of Taipei within Taiwan

Having spent a decent amount of time in Taiwan as a tourist (4 monthsish total), I've noticed a sizable sentiment among locals, both in Taipei and elsewhere like Taichung/Tainan, that a lot of them dislike Taipei compared to the rest of Taiwan - that it's boring/things are unjustifiably expensive/food isn't as good (except re: international food) with respect to other parts of Taiwan, especially the south. I'm guessing that some part of this sentiment comes from the fact that a lot of people move from the south to Taipei for work but even then I was surprised at how strong they held this conviction.

Curious if anyone else has had any similar experiences or has any strong opinions on this topic
