I'm a fan of OnePlus myself. I recently upgraded to the 13 from the 9 and it's been working pretty well so far, especially since I bought it directly from OnePlus unlocked this time (vs. the T-Mobile version of the 9, which came with non-removable T-Mobile bloatware). The nice thing about OnePlus is that their UI is still fairly close to what stock Android is, though then again, Samsung definitely isn't as bad as it used to be in that regard.

Oh, and the battery on the 13 easily lasts at least two days with my usage. And when it doesn't, it recharges insanely fast compared to phones I've used in the past. I try not to do this too often, though, since fast charging like that does wear out the battery more quickly.
