There are a ton of these sorts of SBCs, and they're all more readily available at reasonable prices than the Raspberry Pi. Most have Cortex-A53s, which are in the same class as a Raspberry Pi 3; the RPi4 has Cortex-A72 cores, but for most things that you'll use one of these for, that's not super relevant.
This lack of name recognition is a real pain for people. A lot of folks in the 3D printing community kind of hurt themselves by scouring the internet for marked-up Raspberry Pis from scalpers when a Le Potato or an Orange Pi or a NanoPi or a Rock64 would do just fine. (I use Rock64 boards when I don't need wifi, and Orange Pi 3 LTS boards when I do.) My printer hub is now a Raspberry Pi only because all of the decent touchscreens I found really depend on the Raspberry Pi pinouts to connect power and HDMI, but if you just need a computer in a case, the alternatives are very good and reasonably priced.
