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.
Currently using a Moto G Stylus 2020, this thing has never had major updates pushed, and the last security one was a while ago, it’s pretty decent but has gotten much slower over time and is probably near the end of its life.
The best phone I had was an iphone 7, it was originally terrible, but the it was iOS 12? (13?) that came out and it was so much better. Like you would have major performance issues with this thing before the update, Apple was probably at their peak around then. I stopped using it because it was vendor locked to Sprint, and sprint stopped existing in my area when T Mobile bought them out
