Personally, I'd select them based on suspension kinamatics over any components. Components can be upgraded easily. Suspension linkage layout cannot be changed.
Assume the alu version to have similar linkage design to the carbon one,
Anthem

Hei Hei

Quick glance between the two, Anthem rely more on remote lockout than Hei Hei. Hei Hei has more anti-squat (close to 100%) so, it'd bob less from acceleration without the need of lockout. Anthem, however, should be plusher when unlocked.
Orbea Oiz

Orbea Oiz has even more anti-squat. But it go toward excessive value. Which will result in stiff rear suspension when applying power, especially in very high gear (like 32x10).
So... selection breakdown:
If you like to use remote lockout. Anthem is the better option. It should be plushest unlocked. And you can make it more efficient by locking it.
Fezzari Signal Peak also fit this use case, but lighter (because carbon) and not really more expensive.
If you don't want to use remote lockout, and want suspension to feel good in all condition: Hei Hei. Anti squat value just above 100% should have minimal bob and still remain active on rough trail.
If you don't want to use remote lockout, and want suspension to feel remarkably stiff and efficient: Oiz. That much anti-squat can bite you back on technical climb when rear wheel hit some edge and stall out rather than absorb the hit to go over it. But on smoother trail or road, the feeling of rear end that stiffen up as you apply power can be addicting. If you are into that kind of feel, "
Intense 951 XC" is another option. It's essentially Intense Sniper that sell for lower price at CostCo.
