If I break Innocence and Experience, I'd drop them both to the 2nd tier, with SOI on top of it and SOE second.
But I'll insist, they complete each other.
Innocence has more interesting songs that have a little more richer sound:
Troubles, Sleep Like a Baby Tonight, Reach Me Now, Volcano (nevermind the haters, Volcano is one of the musically more interesting songs they've made since Pop, and it's not a silly fun song either

vs All We Have Left, Book of Your Heart, Love is Bigger... Blackout, There is a Light...
On the other hand, Experience has better songs and are performed and delivered better.
