I like the Arrancar, they help take the series into a place that makes it more interesting.

My favorite one so far is Ulquiorra, he's very reserved and mature, doesn't show his power when it's unneccesary like Grimmjow and Yammy do.

They'll present a real challenge to the Soul Society, and the rest of the cast, especially Ichigo since Aizen is afraid of his true potential.

It's time that Ichigo needs to face his hollow and decide what path he wants to take, as Rukia told him, if he wants to beat the hollow within him, he has to become stronger.
