Captainsim757 vs Level D 767

I used to own LevelD 767 on FS9 and I'm thinking now of purchasing a decent payware airliner. I'm mostly looking for realism and want to know what the CS 757 is like. I would love to buy the PMDG 747, but I never do long haul flights, so don't see the point at the moment. On that note, what is the PMDG MD11 like for realism?
