I'd agree with Soyo. Naked brothers lead singer has absolutely no talent (which brings the whole group down), while the Jonas brothers are so ridiculously overrated, that they have too much of a swelled head, and play worse. After listening to their albums, I felt they BOTH got degeneratively worse as the songs went down. On a score of 1-10, both get a 1.
Then both are TERRIBLE but if i had to pick id say jonas brothers if nothing else becasue i dont want to hear the nbb singer's whiney squeaky voice jst TERRIBLE
