I got a good deal on a Fold 4 and it's been great. It's literally a tablet in your pocket and with multi-window it's about as capable as a PC for most tasks. Having such a large screen and 2-3 apps open at once is great whenever you're trying to get anything done.
Before the Fold though, I also had the Oneplus 7 Pro and I think that phone still looks more modern than anything else I see out there today because of the uninterrupted notch-less display. If they didn't give it up for a hole-punch on the 8 I would have probably stuck with them.
