Lol! Just to mess with Hat, I'm going to suggest Legio Lex Talionis!
In the old campaign from the 3rd edition days the two legions that had the most player involvement were the Watchful Hunter and the LLT. The Watchful Hunter was the legion most active among the rebel faction players. The LLT was most active among the loyalist players. It's not clear if that rivalry survives into the "modern" day.
One thing that LLT has going for it over other Legions is that there is a current PCI mini-Book on the Legio Lex Talionis. If you are looking for more detailed information and some ready made plot hooks it would be a good resource. Also some 5e crunch...
Chris and I outlined the information needed for a Legion of the Watchful Hunter supplement ages ago back when PCI was more actively looking for military unit write ups. The WH is active in current era mods. While originally player created, it's certainly PCI's property now. I'm certainly still happy to promote it though, as it's awesome.

The following are my thoughts and perspective, though Henry and the authors that use them certainly have the final word. I would expect the rivalry continues though perhaps without the rancor it did back in the day. They're definitely the dark hand of Illir in the types of tasks they take on and devoted to Cadic, but it's not "pure" from a worshipper perspective as conceived providing those that follow another god properly honor Cadic as well. Both legions are zealous in their pursuits and their loyalties and they're both back on the same side. LLT's ties to the Church seem to take precedence over their loyalty to the Coryani Empire, but it's been a while since I read the LLT supplement.
One thing that helped make it fun was knowing there were other PCs out there of the same legion, especially when there were opportunities to sit down at a table together. In the 3.0/3.5 days we hand made 3 WH banners. Chris Knight who came up with the legion in the first place has one, I have another and the third was gifted to Henry. Mine currently hangs on our wall. When possible I still break it out and bring it to events. It adds a bit of flavor especially to BIs.
I made quite a few friends bonding over the legion. Regardless of which legion you choose, I hope you have a similar experience being able to bond at a table with others in the same legion or at least in a Coryani legion. If you have any questions about the WH, happy to share what I know.
For duty and honor! (and with a sweep of his hat),
