Do most mums have 2 pumps? One for home and one for office?

I use the Medela Freestyle pump and it's really portable so I just have 1. It's really light and easy to use, plus it comes with a bag, ice pack, and cooler bag so I just bring it with me everywhere. My friend says though that other models and brands (like Spectra) are more powerful so I'd get more milk if I use them. But so far, my supply has met my daughter's demands using just this so I'm okay with not buying a second pump.
