Medela vs. Spectra vs. Lansinoh

I am a FTM and cannot seem to decide between the Medela vs. Spectra S2 or Spectra S2 vs. Lansinoh Signature Pro pumps.

Seems like the Spectra is better rated and liked but the Medela seems to have more accessories that may make storing easier. Medela doesn’t have the backflow protection.

Lansinoh parts seem easier to replace and there are more suction options than the Spectra.

Also, since they all are covered by my insurance, how far in advancerrez should I order? I am due in two months. One month before?
