Sound against the shirt,do you mean the vibration or something? Haha. Anyways i haven't tried a single gloss yet, do they feel smooth as the satin? Do they stick to the right arm when playing??
Some people say they can hear the difference between different finishes, but I'm guessing it would be pretty difficult to do so in a blind test. The difference in sound would be very subtle.
For finishes, non-acoustic preferences probably matter more. Gloss tends to look better to most people since it's shiny. It offers a tiny bit more protection. One drawback for gloss finish is it can react with things like your sweat (making the instrument feel sticky) or sometimes with stands and cases, causing imprints/blemishes. But that's not super common, especially the latter. Gloss finishes are unique to the maker, so it can be difficult to predict what will react with what. I get stickiness with certain brands but not others.
Matte feels better to some people. And it's often a bit cheaper, though not always. No stickiness, no reacting to stands and cases. Sometimes builders will do a gloss finish with a satin or matte neck, so the neck doesn't get sticky. One drawback to matte is that sliding your hand or arm, sleeve or shirt or whatever will often make a little swishing noise that you usually don't get with gloss finishes. This might be undesirable for performances and recording. Some people claim that having less finish like matte improves the sound.
Satin is like a middle ground between the two, but in my experience tends to be closer to matte finishes than gloss. There's a really light coating, more than a matte finish, but it typically feels closer to matte than gloss finish. It usually still has the swishing sound, but also doesn't have the stickiness problem. I've seen matte and satin used synonymously, but any manufacturer or retailer should be able to clarify if you ask.
My own preferences: I have all three finishes. While gloss is pretty to look at, and most of my instruments are gloss, I tend to prefer satin or sometimes even matte finishes.
Oh, also apparently you can sand down gloss necks to make it less sticky if you like, and you can shine up matte finishes by playing on it frequently, like how statues sometimes have shiny surfaces where everyone touches it. I have no experience with either, but I've heard as much on these forums.
