Really depends how you define “better”. MSFS2020 definitely is better looking, though not as much as selected screenshots would have you believe. More reliable, do the planes work ? No contest.
It is fair comment that too much is said about MSFS graphics, and World Updates are just more graphics. The market for X-Plane scenery enhancements is not huge, OrbX do a few but lots just manage with the free SimHeaven upgrades and Ortho scenery. The big sell in X-Plane appears to be aircraft.
It’s not a question of “works like I want it to”. It’s a question of works, period. Many people happily fly VFR in MSFS but abandon it for X-Plane, FSX or P3D for IFR/Airliners - because they work.
Sorry, but what are the “proper VFR abilities” that no other sim had ?
I mean, for VFR you need a plane, some scenery and some weather, that’s about it. In some ways MSFS can be harder, even though it looks nicer, because of the density of trees (set on “low”) can drown things out. Apart from, again, the graphics, I don’t see what VFR MSFS offers over VFR FSX. I actually find for non-cheat-map VFR flying X-Plane easier, that might just be because I’m more used to it.
The only thing MSFS has that is non graphical is a better VFR ATC (and that’s not great, just being slightly tarted up FSX ATC), but it does do traffic patterns now for example.
Standard aircraft in sims are not “barebones”. Even FSX and FS2004 could hardly be described as such. No-one would say FSX was study level, but most of what was there worked.
Comparing the stock X-Plane aircraft to the MSFS ones is absurd. Yes, they have “room for improvement”, but they have and always did basically work. In MSFS the GA bits, and VOR/DME/ADF seem to work fine, the Garmin is okay now.
The airliners are hopeless, better , yes, but still hopeless. (And as we aren’t including mods apparently, you can miss out the A32NX and CJ4 that were done for free by others …)
