Seems to me that the Finnish model is better for an average student (guessing by their PISA test results) and worse for a talented student (guessing by their math olympiad results).
Anecdotally, a Finnish friend told me that if you excel at one subject, you are encouraged by teachers to stop doing it, and instead spend more time learning the other subjects.
