The most popular brands I know of are Medela and Avent. I used an avent in hospital and found it very painful, I own a Medela “pump in style” and love it, it is gentle and easy to use and fairly compact… Mobile too. However it does make some interesting noises. It really is an individual preference though as all breasts are different and what might be most comfortable for one woman will be horroble for another, the best thing you can do is try a few if possible.
