I think the setlist doesn't tell anything about what he likes or what he doesn't.
90 % of the songs are songs that will work in getting a stadium going. Sure enough die-hards hate Cpt. Crash and Who says and Born To Follow. But at the end of the day all of them work in a stadium - everybody's waving their arms, singing thousand "alrights" or let Jon hearing say "yeah, yeah, yeah, oh yeah".
So in my opinion nobody can tell what he thinks about certain songs, as long as they work.

In the When We Were Beautiful documentary he says that it's a struggle between what the fans like and what he wants to play for himself. He mentions that they did the whole Lost Highway album a couple of times, he liked it but the fans hated it. So according to the sets, this is what forces him.

It's a tough question to answer. I'm with bonjovi90 and Becky that he's convinced of the albums the day they are released. But with some years between...I really can't tell.
