Breast pumps advice needed

Hello! Need some advice from experienced mum here on various types of breast pump. I have inherited Medela freestyle, Spectra S1, Youha and Real bubee Breast pump from friends. I only have the machine/pump and will need to get new parts. But I am unsure which one is better as there seems to be good reviews for both medela freestyle and spectra s1. I am stucked btw these two. Then for youha it’s a wearable pump Which I tot will be good once I resume work back at office. Lastly for real bubee i havent see much reviews. Abit overwhelmed too, and not sure for a start which breast pump I shld start using? I also dun wan to overbuy the new parts as they are not cheap so I tot I shld start off with buying for only one brand first.
