This was mentioned is a sibling comment, but I’ll 2nd that it matters more on a bluesy/rock style tone. It’s right when the power amp is starting to get saturated. On a modeling amp, I have not heard one that doesn’t introduce extra digital artifacts into the tone. It’s like the difference between GCI and IRL. Another is on the other end of the amplitude spectrum, very quiet playing, where I hear extra digital artifacts introduced. As the other poster mentioned though, these differences may not come across at all in a metal/pop setting.
