I understand that Megascenery is images only with no autogen so it would be probably cheaper.
. Problem with the Swiss scenery is that the country is tiny and the mountains are very high, which is a bad combination in FSX because if you fly along the mountain tops, chances are high that you see a lot of default scenery around.
On the other hand flying with 500kts through the valleys and zooming up at a 90deg angle with the Switzerland X scenery is a breathtaking experience.
