My experience was obviously different with the 757.  I am just now getting into the 727, and have found it to be of equal quality.  It is a radically different kind of airplane, and not as easy to fly.  You have to use some at least basic radio navigation skills.  You also have to stay after the airplane all the time, because this is old school.  Forget punching in your altitude and leaning back in your seat to watch the airplane fly itself.  You can set your pitch and dial in your nav frequencies, but you are going to have to cover the changeovers from one VOR to the next by switching to heading hold as you pass over and changing frequencies on NAV 1.

In my opinion this is the high-water mark graphically for flight simulation.  I invite your attention to what has been marked for identification as Exhibit A, Eastern Airlines 1976 livery.  A matter of taste, but for my money, there is not a better looking piece of art in FSX.  Even better than the 757.  And a lot of fun to fly, too.  Yeah, you have to keep pouring on the juice all the way in, but you can get kiss-gentle landings, too.

I don't know if I would want a steady diet of 727, but it is certainly my classic short-to-medium hauler of choice.

Personal gotcha: without the electric always on fix my autopilot snapped off after a bit.  So if you're having problems with the rudimentary AP, try that.
