Which Boeing is better?

Asking which Boeing is "the best" is like asking which car is the best without saying whether speed, space, or fuel economy matters. Boeing builds everything from short- and medium-range single-aisle jets to wide-body giants designed for intercontinental routes, and each family was designed for a different purpose.

If the criterion is commercial success, the title belongs to the 737 family as a whole —not to any single version— the best-selling commercial aircraft in the company's history thanks to its low operating cost per seat on short and medium routes. Its current generation, the MAX, has accumulated firm orders for around 7,000 aircraft according to the manufacturer itself, and it is the workhorse of low-cost carriers and domestic networks across half the world.

If the criterion is capacity, the historical record belongs to the 747-8 Intercontinental, with 467 seats in a typical three-class configuration. Its commercial run was short: the last passenger aircraft was delivered in 2017, and production continued only with the freighter version, which was closed in early 2023.

If the criterion is range, the benchmark is the 777X family. Boeing lists the 777-9 at up to 8,000 nautical miles (14,820 km) and the shorter, lighter 777-8 at up to 9,500 nautical miles (17,590 km). Both are fitted with GE9X engines, the largest-diameter turbofans ever installed on a commercial jet, and a large-span wing with folding tips that fold on the ground to fit existing gates.

None of the three really competes with the other two: a 737 cannot cross the Atlantic at full payload, a 777-9 would be uneconomical on a one-hour flight, and the 747 is no longer manufactured. The right Boeing depends on the route, the demand, and the business model of whoever operates it.
