Many serial fans Naruto also agree with this. It seems because SHF Naruto has already released first, even the first series of lininya. Because it is not strange if SHF Boruto has been getting the perfection of proportion and detail.
However, it does not necessarily make this SHF the most perfect. In the photo it appears that SHF Boruto is scaling less clearly. He even looks almost as tall as SHF Naruto.
