Medela...which model?

I'm at such a loss right now. There's so many pumps to choose from. My insurance covers Medela models but I'm looking for recommendations on which models you ladies like and why. I know the Sonata is supposed to be top of the line right now but the Pump In Style and Freestyle models have good reviews too. Can anyone help enlighten a first time mom-to-be on what the difference between them is? Thanks in advance! 🤗
