Just so that no one gets the wrong impression, all of my screenshots feature some form of ORBX scenery. The default trees in P3D especially still look awful (neon green), and I couldn't replace those fast enough (I use the ORBX trees addon). The new P3Dv5 default vector scenery, however, is better and more up-to-date than what ORBX offers, and thus if you own ORBX Global Vector, it is not provided in ORBX Central any longer if you are installing to P3Dv5, since you're already better off without it by default. The world-wide roads, railways, lakes, rivers, streams, coastlines, electrical grid, cell towers, etc. are all more expansive and up to date than what has been provided with the ORBX Vector product - I've noticed in my own local cities, quite a bit more roads and a lot more electrical towers, cell towers, etc., and all of the default airports I've been to have been improved and in some cases there are a lot more airport hangars/structures present now to better match reality. However, I still found the need to install the ORBX Global textures and Open LC landclass & textures, the various ORBX regions & airports, and the ORBX True Earth Great Britain sceneries (all of which looks even better now).
I will say that I had been using all of the various forms of REX sky/clouds/water products for a great many years now, but now I'm not using any of it, as I find it fantastic as is, just default, using the P3Dv5 Enhanced Atmospherics.
