You people should read his abilities section to find out why exactly is a prodigy. But if you are lazy, then again... :
 * Mastered Shadow Clone Technique, an A-rank Jounin level technique, at an even younger age than Naruto did
 * Can use 3 elemental nature transformations at such a young age, Sasuke, another prodigy, could use just 2 elemental nature transformations
 * Learned the Rasengan in fewer days than Naruto did + applied nature transformation to it subconsciously right away, something Naruto had to struggle with by intense training years later

Boruto's talent as a Shinobi are clearly superior to Naruto's, equal to Sasuke's I would say.
