Final Comments: Sunny and Tiffany make up the weaker end of the Girls’ Generation vocal line, although Tiffany is slightly better than Tiffany — slightly. Unlike Tiffany, Sunny hasn’t really shown very much improvement since debut, however she does have a nice head voice (which is fact better than most female idols) and is less nasal than Tiffany. Let’s hope that she actually starts to work on her voice more.
