Door dash has more variety but Uber Eats is better overall imo. Also if you get delivery a lot, if you upgrade to Uber One/Dash Pass it reduces the fees overtime, cooking a little more now though honestly.
I used Door Dash once to order some Chick-Fil-A. I doubt I'll ever use that mess again unless I'm traveling and don't know the area well or got there too late to go looking for food or something. I'll be damned if I'm gonna pay that much for some Chick-Fil-A again. I deleted that app off my phone right after that.
