Granted with GE you should have a good terrain mesh such as FSGlobal. But even with just a default setup it is great.
Personally I run GE/FE/FSGlobal/UT USA&Canada/Alaska, these combined transform the sim into a totally new experiance. And many times I find myself pausing the flight to jump outside and look at the world in a new light

As for Flight1 site blowing smoke i don't see how, they specifically state that the screenshots are taken with other enhnacements, if this wasnt stated then you have made a point

The product does exactly what it states it does and that is improves the Ground Enviroment, add-ons installed or not.
If you were to buy it which I recomend I would also sugggest terrain mesh of good quality (FSGlobal is the best for me) without it you will have a greatly improved flat world
