Why save her? Because she should be easier to beat than many of the others. Let the better cooks fight it out in the pressure tests and keep someone that you are pretty sure you can top in almost any challenge. She does seem to find a way to botch assignments, no matter what they may be, all the whole being totally delusional about her ability and playing the "No one ever likes me!" card Watch yourself on TV with an open eye & ear and you'll soon figure out why, honey!
If viewers find her annoying, I can only guess what it must have been like being around her 24/7 during taping of the series.
That said, the decision about who would leave held no suspense for me. The hunter-mom, six-kids, dead-husband woman has gotten too much screen time/backstory build to be an early eviction.
