I spotted a tutorial on YT, modelling a keyboard Synthesizer. The Instructor (which actually says in the beginning is a novice blender user)is constantly using Boolean Operation to cut into the main shape, saying that Ngons wont matter, and if using another method loop cuts to make quads would take for ever. So would it be any benefit of me watching this tutorial or would it lead me astray from correct 3D modelling approach? Or are the Boolean cuts safe to use as long as there is no subdivision surface modifier applied to the mesh?
Thank you.
