Great action, nice and slick, tons of prefit barrel options and swappable bolt heads if you get bored with .308. Most importantly, Zermatt has phenomenal customer service.
I've had multiple zermatt and defiance actions. Currently own a tl3 and a rebranded deviant. I'll take the tl3 over the deviant any day. Same for the origin over the classic.
Swap bolt heads (for 150 instead of 350 to 400) and barrels whenever you want. CRF/ME action let's you run any case length you want (I love 6br).
Zermatt just plain works.
*full disclosure: I actually like ARC better than both but you didn't list them.
I say go with anything from Zermatt, I’ve been running an origin since its release in like 2018 and it’s never let me down. The only issue I’ve ever had was bending the threaded stud that attaches the bolt handle to the bolt body, granted I literally had to beat the bolt open with a lump hammer due to a unsized case getting jammed in the chamber. I ran the rest of the match without a hiccup and eventually replaced the extractor at the end of the season just for a piece of mind after I was sitting in the spare parts kit.
I’ve also been running a RimX since its introduction and a TL3 since 2019, both having a ton of rounds through them without any issues.
