Breast pump

Kim
My insurance covers two different pumps. Looking for suggestions. Hoping to not need it but my son couldn't ever latch so I'm just covering all my bases for my daughter in case she isn't able to either! 
Also if the Ameda pump what bottle or milk bags did you use??? I see they don't come with nipples. 
So 
Ameda purely yours ultra (comes with everything in picture)
Or
Medela Pump in style advanced breast pump STARTER kit (only comes with the pump and bag)
