not specific to acoustic or electric.

Usual things like power chords generally used more on electric.

Lots of differences even around the same subjects like using base notes, arpegiating, introduction to chords, strum patterns.

There enough differences for anyone inbetween GF2 and experience level 1 to go over things again.

Better or Worse can only be according to individual bias and opinion.

None of it is compulsary, so give it a go, try the bits you might like and skip any bits you feel really confident with.

Just 2 styles some of which will suit some individuals better

Very enjoyable going through the new GF 1&2
