which pump and why?

I am learning about breast pumps for when I return to work I work as a medical assistant and will be working about 12 hour shifts I have access to connect my pump to wall plug and I am planning on breastfeeding when I am with my baby and bottle feeding for when I am away but If I am around he will feed directly from me

reasons why I like spectra

night light

rechargeable battery

easy to clean the top round part

cons- parts i need to order online and one store in my town sells the parts

reasons why I like medela

it's been around longer

parts are easily found at Walmart target Walgreens

bottles are compatible different brands

cons not rechargeable incase I travel and need to pump unconnected to wall plug?

I can't decide insurance covers both
