Oneplus has gone to shit as far as software is concerned, but the hardware is still good, so if you're OK running a custom ROM, they're good.

I last used the Xperia lineup ages ago, but it was a pretty decent experience, close enough to stock Android and the additions they did add were actually improvements. No idea if that's still the case, but you could look up some reviews.

Ditto for Motorola, which was nearly stock Android back in 2014.

Murena sells refurb and new phones with /e/os preinstalled if you want to go google-free.

I do miss the early days of Android, when you had players like HTC creating completely unique Android experiences (I mean so did Samsung, but their uniqueness was how slow Touchwiz was).

Edit: Also completely forgot the fact that Nokia makes some good phones, including pretty affordable ones and some higher end ones. But personally the one person I knew with one had issues with the USB-C port and had to have theirs repaired by the warranty and then refunded on the second or third round. But that was a much older model, maybe 5 years now, they likely have fixed the issues on their newer ones.
