You're entitled to your opinion but it might help your case if you gave the reasons you feel this way.

If you don't respond your post will be hidden.

Rex weather has five years historical weather, rex has better clouds , rex is in msfs since three years ago

I'll leave others to discuss the differences with you. Bear in mind the difference between opinion and fact.

No METAR and PRESET based WX will be able to get you anythning near to what MSFS currently does (read PRESET based!).

One airfield has few clouds and 20 miles away on another airfield you have incoming storms. So you will have to aply 2 presets (which can not be done) at this time.

E.g. I constantly fly to Romania Timisoara on business. At this time both REX and AS show a "sunny day" over the Airport because the METAR says so. But just few miles away, you have a closed cloud covarage which brings rain. Gues what the sim shows with REX and AS ;).

Only MSFS depicts this closest to what happens in real life. Is it spot on all the time? No, but I tend to accept the general weather coverage idea more the a METAR PRESET based WX.

My 2 ct.

Couldn't agree more 3d party WX apps are useless here local when the WX API isn't accessible to them...

When was your last flight with REX from A to B through weather? What was specifically the issue. I continue to have good luck and I am wondering why?

[GEKtheReaper 375]

@cchiozza you got it wrong. Let me ask you something: In your flight from A to B did you use webcams in the sky to check if the reported weather is actualy drawn? <- this is a bit sarcastic.

Do you understand what weather presets are? E.g. you go in MSFS and pic a weather setting e.g. Clear Sky. Looking all around you you will see that preset. If you want to change it you will have to go again in the weather tab and take the storm preset....ergo...anything around you is going to be stormy.

This is exactly what todays WX generating APP (REX and AS) are doing automaticaly for you. They do not have just 6 presets but extremely many and they apply a preset that best matches the METAR were you are BUT IT DOES IT EVERYWHERE around you! If you are on an airport with clear skys and as I said earlyer 50 miles away there is another airport reporting inbound storms, you will initially see nothing on the horizont taking of from your clear sky airport. Getting closer to the "stormy condition" airport, a transition of weather themes will occure but it will change anything around you into that METAR preset.

So if you just fly from A to B you will probably enjoy your flight and see some nice WX around you. You like it, enjoy it!

MSFS uses a GLOBAL weather model. So basicaly they know every weather station (meteo blue) around the planet. They create a global "world wide" weather and in such a case you will probably see the storm clouds already in the distance. Because the model a global based weather, there are cases where the drawn WX differs (more or less) from the local METAR report. I currently want this GLOBAL representation instead the local representation.

Above explanation is a raw representation of the current state until MSFS opens up the API (if ever).

Just another example: I live in germany S near lake Constance. Near me is EDNY airport. Over the lake you will find the Swiss Alps (mountains) and a small aiport LSZR. You have pretty frequent clouds in the Swiss Alps region and clear skies on the opposite site of the lake. You show me how METAR based WX draws that in MSFS.

Hello, for ME ASFS is the winner,

because the change from one weather area to the next can be displayed more smoothly. Furthermore, I had stutters during weather changes in REX. I don't see any of this with AS.
second is i can use MSFS Weather depiction with Turb in AS.

Understand your presets comments but that is not what I am talking about. MSFS weather metar may "use" it as you say but the depiction is marginal at best. For instance flying near a moving from with thunderstorms in it rarely show multi layer clouds or even thunderstorms for that matter. REX does very nicely. May that's has been the focus of my testing. I fly mainly in the US so this might be the disconnect. Ill will try your area for fun. But this while Mateo blue weather has never been what it was touted for sure.

Are there ANY multi layer clouds. All I have seen has been one level. Would love to hear if you have. That the reason why I did not purchase.

The live weather provided by REX is not predetermined in any way, or preset-based. It's continually evolving based on real-time processes.

How is Performance with REX weather ? ( FPS ) 

Used to be very poor when weather was updating, but very good now.

Clearly a global weather model is more important to you. It is important to me too, but at the moment we can't have a local model AND varied and realistic clouds.

Either you see cumulus in the distance (which is a very poor representation of a front), or you get more realistic multi level clouds with a global weather model addon 

Both can be called realistic, but you choose the option best for you.

You are correct that the latest REX is very good.  Your opinion of ActiveSky is is very wrong.

Maybe you misread / misunderstood what I said. How do you change weather without MSFS opening up the API? Don't you read the METAR data along the way and apply the "scene" that is most accurate to the METAR data?
