Diva cup vs. lunette cup

So I've been researching menstrual cups the past couple days and I really want to get one. I cant deside if I just want to go to Walmart and get a diva cup or if I want to wait and order a lunette cup. From my research ppl seem to really like the lunette more then the ppl that like the diva. So I was just wondering what your opinions were. Thanks you 😊
