Fingerpicking style songs.
Or let the bass do the rhytm, and just bring the guitar in for som fills,
bridges and solos.

I disagree (in this case). Of course full chords give a better overall sound by highlighting the major, minor 7th etc... tones, but not in Rock/Metal.
If you think about it rock and metal songs are mostly riff-oriented which sound best with power chords. Also this type of band tends to use the guitar with the gain/distortion RIGHT UP, which when playing full chords makes the overall sound bad, tacky and well...distorted. So basically yeah full chords are much better, but not when it comes to rock and metal.
