This is really a matter of opinion and programs. For example I'm not excited by Hanyu's SP (although his elements are exciting to watch) but I am excited by the attack and drive shown in his FS, due to the nature of the program and the character being portrayed.
Chan's FS I don't find as exciting as I found Four Seasons, but it's more interesting to watch, and the level of skating ability is (somehow) even more improved than a year or so ago.
And if we're talking about exciting in terms of ability to engage an audience, then it's hard to argue that Chan isn't exciting. A skater wouldn't consistently get such high marks for Performance if he wasn't an exciting skater. In your opinion, he isn't exciting, and that's fine. But the vast majority of the skating world disagrees.
Also, if we're talking transitions, both have them throughout their program. Hanyu has more within his elements, Chan has more transitions in between his elements - and more interesting transitions at that (IMO).
