I'd rather see Rachel go. Right now Annie's in the middle of a perpetual nervous breakdown over the eviction that's still three days away. From a viewer's perspective this is more entertaining than the feeds have usually been so far, even if she's kind of annoying.
From a strategic standpoint, I still think Rachel should go. Annie has basically no one's trust in the house, she can obviously be broken down, but Rachel's only game has been to try to keep a shut mouth. She's in an obvious alliance with one of the biggest threats in the game, Brendon. Nipping those relationships in the bud can be a good move. Just look at how far Jeff and Jordan got. Just imagine if Rachel rode Brendon's coattails to a win like Jordo last year. Yucky.
