[snip] The stated motivation for Ariane 6 (as of 2015) was to halve the cost compared to Ariane 5, and increase the capacity for the number of launches per year (from six or seven to up to eleven). [/snip] https://en.wikipedia.org/wiki/Ariane_6
Meanwhile, Falcon 9 is reusable, has made more than 250 landings on the drone barges, and thus far this year has been used 68 times, as compared with 96 launches in all of 2024. Here and there Falcon 9’s have been used in expendible mode and were intentionally not landed or recovered. I think all or most of those had been used and recovered in the past. Expendible launches don’t save fuel for landing, and are implemented for the heavier payloads.
[snip] Falcon 9 first-stage boosters landed successfully in 326 of 337 attempts (96.7%), with 301 out of 305 (98.7%) for the Falcon 9 Block 5 version. A total of 297 re-flights of first stage boosters have all successfully launched their payloads. [/snip] https://en.wikipedia.org/wiki/Falcon_9#Launch_history
And starliners failure rate is now 100%
