I dunno, I think Messiah works as an ending to the trilogy. There's quite a bit of intrigue and action. Nothing gets too weird—Duncan's Ghola is the only new sci-fi addition.
Children takes a sharp turn with the whole possession thing and then Leto's metamorphosis. But Messiah is quite adaptable and is the real ending for many of the same characters as Book 1.
