I like Leno.  I can't stand Conan...  in fact, I quit watching the Tonight Show when Conan took over. (maybe I'm one of the reasons the ratings are dropping? BTW,  the late night shows had absolutely no effect on whether/which late local news I watch..).  So, now I watch the local news, then switch over to watch Nightline on ABC, then Jimy Kimmel.  He's okay, but not quite as good as Leno. 

BTW, 2 nights ago, Jimmy Kimmel did an impersonation of Leno during the whole show.  Last night he said that the Leno show had contacted their show yesterday - after he did the impersonation - and requested that Jimmy Kimmel be a guest on Leno's show tonight (Thursday night).  Stay tuned...... we'll see if this happens...... could be an interesting segment if he appears. (I think he'll do it - that's my guess. He was a guest on the Tonight Show with Jay Leno back when the TV industry went on strike.)
