Buy on Steam or Windows Store?

One major plus with Steam is the built in voice chat via the Steam overlay if you have other friends with steam that play.

 

Otherwise you will need to use mumble or discord for voice chat...

If you get the Steam version just remember to never run the file integrity check (unless you like doing entire reinstalls). Patches and updates come about 30mins-1hr. after the MS version.

 

With the MS Store version, you are tied to the MS Store which likes to control the installation path into an encrypted place. One benefit of the MS Store version is if you also have a Xbox then it's been noted that MSFS will be part of MS play anywhere (Xbox and PC) which if you get the Steam version it's PC only.
