For a long time your options were a closed source driver from nVidia that worked, an open source reverse engineered driver for nVidia cards that didn’t work, a closed source AMD driver that wasn’t very good and lagged behind the PC version by a big distance, or an open source AMD driver that lacked many features and didn’t support the newest cards.
Maybe in the last 5 years things have started to change, but for a long time, if you were willing to use the closed-source nvidia drivers, they were just the good option that worked for most cards.
