You are right, La Candelaria have some really amazing pieces, I remember that... But Mexico also has a lot to offer. I saw some stunning pieces on the Mexican island of Holbox for example...

...and the city where we lived, Playa del Carmen, also boasts many cool murals:
As for Prague and the John Lennon Wall, it´s true that it´s the most famous street art spot in the city but unfortunately, these days, the wall is just full of ugly sketches and poorly designed signs... There is nothing artistic about it anymore.
