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.
