Compared with these three places, the universities in Xiamen seem to be the best. Xiamen No.1 Middle School and Shuangshi Middle School have a high enrollment rate, as well as Xiamen University and Jimei (this is a university).

There are three kinds of high schools attached to Fuzhou, all of which are good. No.1 Middle School is similar to Xiamen No.1 Middle School. Fuzhou has Fuzhou University and Fujian Normal University.

I don't know from Putian.

But I think Xiamen is the best in terms of learning environment.
