That’s a valid point, no need to switch as long as you’re happy with the other products out there. I actually hope that one day we can have realistic carrier operations (and air-to-air refueling) in MSFS as well. No need to simulate combat scenario’s for me (that’s what games like DCS are for), but it would be great to simulate peace time military operations like close air patrols, intercepts and weapon training scenario’s. Maybe even an air show from the Blue Angels.
Now don’t forget that the F18 and carrier operations were actually part of an expansion pack (Acceleration pack), so there’s still hope they release a DLC one day that supports peace time military operations. Maybe they can do something around the release of the new Top Gun movie, that will surely attract a lot of XBOX users to MSFS 
You’re actually commenting on one of the few things that caused a little disappointment from my end too and that’s the quality of some of the hand built airports, especially EHAM. Now I didn’t expect full payware quality from these airports, but they could have been a little bit more detailed. I guess they didn’t want to mow away the grass from the 3rd party developers, just look at LOWI which was part of the standard hand crafted airports and which was released pretty soon as a payware expansion from ORBX. There might have been a conflict of interest at work between MSFS and 3rd party developers in this area.
Seasons will come though, that’s actually on the road map for this year and they already started development on that. You can even have seasons already if you are willing to pay for an add-on. But let’s be fair, the snow simulation with different depths of snow and live snow coverage around the world is already pretty amazing.
