I was fortunate enough to work briefly with the Flight Test Department at a previous company I worked for. We had B-737, B-757/767, B747, DC-10 at the time. I was able to make it in the jumpseat on several test flights, several on the B-737, one on the B-747 and several on the DC-10.
The B-737 stalls like a really nice flying airplane should. We didn't bring the 747 into a stall for the test run I was on. However we did stall a DC-10 when we had to re-certify the AOA/Stall vane. It was a very - VERY interesting experience and I can tell you that a DC-10 acts far different (think nasty) than a 737 when you start talking about departing controlled flight.
In a discussion after the test flight, the lead test pilot told me about stall characteristics of the various aircraft he'd tested, and was very favorable about the 737 and the 747 as being fairly conventional. He did not have the same comfort level with the DC-10 or the DC-8 from years previous. He mentioned the term "slicing off to one side", meaning a pronounced yaw or almost "flick stall" toward the edge of the envelope when discussing the DC-10, where he wasn't too concerned about the 747.
