10 was on the x98 air 3g I bought and wifi didn’t work with my router (anywhere else I went it worked) but it worked on 8.1. There’s less optimization steps for setting it up (not having to run additional software to remove telemetry, I already know what updates to hide in 8.1), being able to choose “update manually” without 3rd party software / registry tweaks. it’s more that I’m happy with what 8.1 offers and not wanting to deal with other issues to gain features I won’t use. that and the plus uses the same WiFi card as the air 3g and I don’t want to deal with “cannot connect to network”
