In general you should aim for the most comfortable position that allows you to play in a relaxed & efficient manner.

As to what you observe other guitarists doing, I think a few thing factor in. Often sitting is the best way to ensure a good, stable video recording. You are less likely to move around & get out of the framing position if you are sitting in a stationary seat.

However, if you are used to playing while standing (in order to perform), often the guitar lays more comfortably on your torso in a position that makes the entire fretboard easily accessible to your hands & your picking hand fall naturally near the bridge. In order to make that position work while sitting you move the guitar body more naturally to your picking hand.

Otherwise you wind up stretching your fretting hand way too far to the left & your picking hand across your torso to meet the guitar instead of holding the guitar to meet your hands. Make sense?

The style of music also factors in. Most rock, blues, pop players are using guitars that work well on a strap hanging on your torso. And they are expected to stand on stage & walk or run around while entertaining. And the music itself requires bending strings, barre chords & other techniques that work best when you are able to hold the neck away from your torso for more leverage & access.

You will notice classical players almost always sit. They are expected to sit & focus on the music & not jump around in order to entertain. And that style lends itself very much toward the classical sitting position for best playability. Jazz players also. And when they do stand with a strap, you will often see them hold the guitar neck up quite high & picking position to match the sitting position.

I usually have my strap set at a height that works for either sitting or playing.

[quote=jayyy]because I cannot get use to it and feels less ideal than the "classical" position espectially when moving up the neck.

You should do what works for you! Hope that helps!
