Though I'm more on Naruto's side when it comes to things, I would have to say Uchiha Sasuke is more full of sorrow than Naruto.
One thing is, that it's much harder losing a family you've known for years than it is losing a family you never even have a single bit of memory of.
Sasuke practically saw his own brother kill his entire clan, which left him petrified with questions of "why?" at such a young age.
As for Naruto, he never knew his parents, and even this far into the manga he probably doesn't know who his parents are.
But Naruto's sadness is revolved around the people who knew something he did not, while Sasuke is revolved around witnessing the slaughter of his family. The lost of your entire family is much more saddening than being ignored and treated like an underclassmen.
