The 737 hides a great multitude of sins with that landing gear. It casters. So, a bit of crab, or drift on touchdown, and the Guppy hides it, making the pilots look good.Not everyone is that snippy. I recall LAS-OAK going home with the family on a Christmas day. Raining buckets outside and the wind was just nasty that we could tell that the pilot was fighting it. And of course a 737 which I get that you don't like for its stubby landing gear. We didn't land smoothly, but as soon as we figured that we were down safely, passengers started to applaud.
What would be a smooth touchdown in a 737 can be a lurching, uncomfortable landing in a 757/767. With landing gear that actually works (you know brakes, long enough to prevent the tail from striking, etc.) you can't hide that like you can on a Guppy.
