I bought an RPi 4 with the goal of streaming my Android screen using scrcpy but that turned out to be horrible. If I'm not mistaken, the RPi 400 has the same hardware specs as an RPi 4 (minus the keyboard) so your experience would mostly be the same on both. After a while, I realized that an RPi 4 is a terrible device if you intend to use it as a desktop. Either hardware acceleration won't work and even if it does, YouTube will lag like hell on 1080p. Forget YouTube, even stock XFCE with hardware acceleration is not as responsive as it would be on a meager Celeron/Pentium potato. The cost might justify using RPi 4 as a desktop for some people but if you're not restricted by cost, don't buy an RPi 4 to use it as a desktop. RPi 4 can be a great choice for a headless server though. I use it to run AdGuard Home to block ads on all of my devices. I'm also considering buying another RPi 4 to use it as a router and another for using a e-Ink screen to show time.
