Moi? I use currently a NOTE 20 ultra 5g. Probably my second best phone, I only hate the fact it’s so massive (I miss being able to use just one hand for my phone) and the mediocre battery life for someone like me that watches a lot of videos. But the S pen is so handy those few times you need it.
Samsung S10 here. It needs replacement or LineageOS.
Best phone? I LOVED my Nexus5. Oh man, was that a great phone. Before that - get ready - StarTAC 7800: a feature-flip. Not as indestructable as my micro-TAC 550 but still a great phone.
