Because it has 3 colors. Sometimes you can put them in two colors. For the Pwnagotchi project, the consensus has been that the Waveshare B&W v2 is the best [1].
Based on my own experience (I have one) I can say it has a high enough refresh rate, and little ghosting (none is impossible as costs too much battery to do full refresh).
Also, the UPS Lite, also from China (AliExpress or whatever), is excellent.
Do keep in mind this is a specific/different project, with a much smaller screen, meant to be portable (for on the go).
