Funny, I actually decided to shave my head for the very first time in my life 2 weeks ago partly because of that and I love it.
Not sure if those numbers are universal or if it's just a Québec thing but I basically got a "#1.5 cut" which, after two weeks, is now looking more like a #2 cut.
Technically you obviously see more skin than with longer hair but you see it evenly so it doesn't look as bad as when you have a ton of hair everywhere except on top of your head and in the back of it.
I wouldn't want to go completely bald/shaved (like with razor and shaving cream) but I love the buzz cut.
Also, I love the practical side of the new haircut. Much better at the gym, hair is dry instantly when you get out of the shower and never have to worry about you hair looking messed up after you remove a cap or headphones.
Btw I'm a 32y old overweight dude.
