    I try to understand 20° or 25° is better. It's just internal feelings or, for example, smoother idle RPM?

    It's your engine, try it & see. With the Sniper controlling timing it only takes a couple of seconds to try different timing curves. You can even drive down the road and have a buddy change the timing as you drive. Spend an hour trying different timing curves in your engine and you'll be an expert.
