Didn't he say Chouji was?
I find it laughable when people think Sasuke is his favourite because of how much "shine" time he gets. Like really? Are you reading the same manga?
Sasuke has taken the backseat for almost the entire war! He took the backseat to Kabuto and Itachi, he then took the backseat to the Hokages and Hashi/Madara past. Even when he "got his time" he was team-working with the others so people say "he can't do that alone"
He hasn't got time to really shine yet, not like Naruto has when he went all Bijuu Mode for the first time and raped shit. He hasn't had anything like that. Heck, he got solo'd NEGATIVE difficulty. We haven't even seen him going ham with PS on his own yet...
The last time he was really in the "spotlight" was his fight against Danzo.
