There are many different types of tutorials for drawing virtually everything as there are countless different art styles that people have developed to what they think looks best.
Above is a tutorial that looks like it could be from a superhero comic. The style is kind of realistic but has a kind of cartoony feel with the nose / chin.
The tutorial above looks like it could have slightly been inspired by manga with the eyes being its largest and most distinct feature.
Out of the two tutorials above I would personally say I prefer the second one because the lines are much smoother and it is just much more appealing to me. But I think this is purely based on someone’s personal opinion as I prefer manga style drawings over comic drawings as I read a lot of manga when I was younger and rarely comics.
