Emby doesn’t have good apps for as many platforms as plex does. I use plex on my PS4 where Emby doesn’t have an app.

Yeah, this is probably the main reason. I know two friends who use Plex exclusively on their PS4.

I'm also not the only one in my group maintaining a Plex server, so they'd incur a transitioning cost as well.
