Possibly a feature of the single-axle 737 undercarriage whereas the 747/757 have twin-axle bogies and a necessarily more complex suspension. The Tupolev Tu154 has a triple-axle bogie and is even more so, every landing I have ever had on it has always been a greaser. In fact, Russian pax who have been familiar with the 154 for years comment adversely on the landing thumps of the 737s now coming into general use in Russia. We here know it's not an issue, but it's still a thump.
