I'd prefer a spring. Atleast for my fridge the beeping isn't pleasant as an autistic person. Any situation where I need to keep the door open I could figure out a work around like using my elbow or asking a friend to help if I really couldn't do it. The beeping I can't work around and if I managed to remove it, which I doubt I could do, I wouldn't have anything to close my fridge or tell me when it's open
