Ok I have finally settled for Mster's config since the quality/performance was probably the best. CCC had nearly identical performance, but they just exaggerated the colors/bloom too much for my taste, making many scenes (though not all) looking too unnatural.
I'm gonna try to fix the issues I have with Mster's config manually then but editing it where necessary, though I'd rather touch it as little as possible. Really need to fix the water and the night. Will ask question here if I need help and let you know of my progress
