The obvious and only correct answer, according to Hide standard wisdom, is BUY BOTH!!
All kidding aside, I have both. I started with the Origin and then bought a Solus on sale before they hired that idiot to manage their operation. I bought it because of the 60 deg throw and the fact it uses the same prefits as my Origin. That said, I would recommend for your first custom action that you buy the Origin over the Solus. The Origin is a nicer feeling action, the customer support is worlds better, and the resale, if you ever want to sell it, is solid. Good luck getting parts for anything Aero makes, I’m still waiting for them to release the folding adapter to their chassis and they announced it as a product in 2023.
Go Origin and never look back. If you want to build a lightweight mountain hunting rifle, look at the MacBrothers Element, it weights 19.8 oz.
