Can I go straight from the Saucony Triumph 18 to the Triumph 20 and skip the Triumph 19?

Yes, but going Triumph 18 to Triumph 20 means taking one change in a single step: the Triumph 20 is where the ride moved. The drop also goes 8 mm to 10 mm across the jump, so give it a week of easy running.

How much did the weight change across these two updates?

1.4 oz off in total, 11.1 oz to 9.7 oz in a men's US 9. The Triumph 19 took it to 10.2 oz first.

Is the Triumph 19 the better buy than either of these?

On paper it splits them: 10.2 oz against 11.1 oz for the Triumph 18 and 9.7 oz for the Triumph 20, on a 32.5 mm heel and a $150 list price. Availability decides it: Amazon's Triumph 19 stock is gone in both men's and women's sizes, so it is not a live option.

Did the Triumph get taller between the Triumph 18 and the Triumph 20?

Heel stack went 32.5 mm to 37 mm, by way of 32.5 mm on the Triumph 19. Drop moved 8 mm to 10 mm, which is the change your calves and Achilles notice.

Where does the Triumph 20 sit in the Triumph lineup now?

Two versions on from the Triumph 18, and already replaced itself: the Triumph 21 arrived in 2023. If you are shopping old stock anyway, price the Triumph 20 against it before deciding.
