Best breast pump to get for preemie triplets??

Hi! My doctors gave me a prescription to get a breast pump and I want to be able to get one by beginning of December . Is there a specific one that’s best intended specifically for triplets ? Does a certain brand benefit the mother who delivers at say, 28 weeks instead of 32??

I want a wearable one but was also told it’s not as powerful as a traditional pump . But I also will be returning to work after 6 months of delivering my triplets (whenever that will be) so it would also make sense to have a portable one??

Unless I should use the prescription for one with cords and buy myself one that’s wearable?
