Dell still has models with barrel chargers. Some of them do support USB-C charging as well but only have one USB-C port. I own one of those, regrettably.
OEMs have always made better phones than Google themselves by improving and enhancing Android. Many improvements to Android came from Samsung, HTC and Motorola - the OEMs. Post 5.0, Google has only ever made improvements to Android to benefit its own hardware and ecosystem. For example, the Galaxy Nexus had no MicroSD slot even though the Galaxy phone it was based on did. Even now, Samsung is offering a phone with a headphone jack whereas Google has made their last two phones without, in a completely anti-consumer move.
Today's "Samsung crap" is tomorrow's "Brand-new Android feature that you need to enable Google tracking to use"
