Arguably at most third place, since partly reusable New Glenn (Blue Origin) is already planned to launch in a few months, currently September. Though lower stage reuse might only happen later.
Ariane 6 isn't significantly ahead of New Glenn in terms of time. Probably a few months difference for date of first launch. Just as Vulcan launched a few months ahead of Ariane 6.
New Glenn is a ground up unproven design. Ariane 6 is an incremental improvement from a well proven and highly reliable rocket. Just because they’re both making their first flights doesn’t mean they’re comparable as commercial offerings.
The cost to build a satellite is high enough that most customers don’t want it to explode. Until New Glenn has a solid track record they’re not really comparable.
