737forever -
I'm not a fan of saying the 727 is the best ever. At it's time it was a great airplane.
757 IMO outperforms it in reliability, climb performance, short field performance, high altitude capability, hot and high performance, is much quieter, better thrust to weight, and more efficient. Every thing related to safety, except a third, older engine, is better on the 757.
The 727 is faster(.885/411 KIAS

). The 727 can be a handful in the pattern and is unforgiving of poor landing technique.
I enjoyed the 727 but don't miss it. To me it's like people talking about the 1964 Opel they owned, "best car ever", when today's technology is clearly superior.
Best handling airliner? Eight different ones so far and for me the A300 had the best combination of light, and balanced, controls. That said, I'd take a 767 over the A300.
