Human eyes can make a difference up to 20 fps, so visual delay between 60 and 120 is careless.
Personally I didn't appreciate any networking delay but if any, it is a secondary issue compared to the huge FPS drop I experienced with VSync off.
Of course if there is a way to keep 125 fps and no drops, it is really welcome, but the above solutions didn't work for me.
