The PMDG T7 has a striking interior; very sharp textures, with beautiful variation in color and contrast. Great exterior detail. Top notch interactivity with easy to mouse-manipulate switches and dials as usual. Systems certainly are thoroughly rendered, though I haven't read any of the manuals. FMS is very similar to NGX, with some variation in automation that will probably require digging into some manuals. Hand flies very nice, great sounds, but a bit hard on my system, so some scenery has been disabled - photoreal stuff.
I had no intention on buying it except out of curiosity, but it really is obviously their best work, a notch up, beautiful to behold and fly. Long distance hauling always ends up with some kind of sim error for me, so some tweaking is in order. I don't think it will work well if you must run lots of addons, such as a combination of hi res clouds, ground textures, and fancy airports all together. I hate to do a bunch of tweaking for one aircraft, so that may end up limiting it's use.
