I don't know which ones you guys are looking at exactly, but most of those Dell refurbished laptops are ~7 year old machines with the bare minimum specs, and the prices are not good (at least the ones I looked at on the first few pages). Couple hundred more gets you into a 2019 machine with much better specs and probably half the weight haha. Just make sure you know what you're getting - I am surprised they have stock that is so old.
Edit:
This this is enormous but look what you can get for only $579:

If you don't mind a little meat on your laptop that is incredible value.
