Picking out a breast pump.

I feel like I'm making the hardest decision of my life right now picking up the best breast pump for me. I have heard well things about both of these Brands but I really would like to hear from anybody who has use either one of these. The breast pump is free through insurance for me which is the big save. between these items I will save between s100 and $250. Which one have you used in did you like?
