If I were looking, my first choices to look at would be (in that order) Weatherby (S2 or Vanguard), Remington, Savage, CZ.
I don't particularly agree with your ranking here
I have a Howa 1500 in 308 win. Which as far as I understand is the same as the Weatherby vanguard. I have also tried lots of savages and some remingtons too. I just got my first CZ, as seen before in this thread, and I must say everything about this weapon feels slightly better than in the other brands mentioned.
It is free floating, the wood is great and the overall fit of the stock is great. The action is great, made to fit the short 223 bullet. It has not had any issues with ejecting and reloading. (I have only shot it twice. 38 shots only) Basically I got a total crush on my new weapon.
And the trigger gives me confidence.
The only draw back is the bolt lift clearing the scope. I had low rings, and I couldnt use them, used the ones that came with the rifle, and without extra cheek support it's no good. But there is lots of bolt, so it can be shaved down to make clearance. But I will keep it as it is. My eye is flush now.
I still want a S2 though, in a medium game caliber, but based on my experiences with the Howa 1500 the CZ seems better to me.
Edit: My ranking would be: CZ, Weatherby Vanguard/Howa, Savage, Remington. Based on the rifles I have tried.
