Not sure what the "what matters most" percentage breakdown would be - maybe there's an SAE paper study somewhere to quantify it. The SAE "Bus Study" did concluded more efficient oil filters result in less engine wear. No surprise.
I'd say running the very best oil in the world with no oil filter for 10K miles would be worse for the engine than running it along with a high efficiency oil filter. Even a less efficient filter would be better than no oil filter.
No matter how it's sliced or diced, less debris in the oil means less engine wear, even if you use the best oil in the world.
