It seems like both p3dv5 and ms2020 were rushed out to compete with each other.
Personally i don't think V5.2 still is a beta, the cloud thing still is but the rest isn't in my opinion . Also because you can use the EA without the clouds now. I do think it was rushed to compete against ms2020, witch is a bit odd because they are not really competing with each other...or are they...
MS2020 was a new product they rushed out of the door to be head to head against V5 i think.
For me , being a professional pilot and having spend hundreds of hours in full flight simulators, i can confirm that a professional sims visual is no where near as detailed as most eye-candy pc sims are. They are getting better but they all have the "Standard" world , like p3d has and you have to pay for enhanced airports , just like we do.
They are about systems, flight characteristics, and the feeling of flight that requires a smooth!!!! stutterfree visual system!!! not the stutterfest clips that i see most of the time on youtube with everything maxed out.
Remember that with zero flight time training the first time you actually see the real aircraft there are passengers on board so the sim has to be really good!!!!
Training has progressed or rather changed a lot over the years. You used to get weeks of groundschool 15 years ago, no you get a dvd or usb stick with a CBT program on it that you do for 2 days and then straight into the sim for the minimum amount of hours that they can legally give you to get qualified. A lot of your own time is invested now in typeratings ( and money as well in some low cost airlines) .
For me in my home sim its about the feeling of flight and not the eyecandy.
