Theres no fair comparison to compare Punk and Metal. It is indeed apples and oranges. Besides I think labeling things really sucks, why can't you just hear something that you like and not even bother to label it as punk, metal, nu-metal? The guitarist from Helmet is considered a punk guitarist yet he is a music professor that can seriously shred. Labeling stuff kind of limits you in what you want to do and thats a bad thing when you are a guitarist. Trust me I went through it thinking "oh I can't write this, it's sounds too metal or not punky enough" years ago I learned that labeling stuff only stunts your musical growth.
I know people to this day that hear something and like it and find out it's considered Punk or Thrash and they suddenly decide they don't like it. That's sad.
So to summize. Neither are better than the other IMO.
