if it has a shorter scale, the frets aren't as long, so I suppose it would be slightly easier to make chords with. whereas with a longer scale neck, the frets are a bit more spaced out, so when you get up high on the fretboard it's easier to fit your fingers in the frets. but seriously, it's just more of a preference thing. I prefer the shorter scale gibson type (haven't tried PRS yet). also, guitars with a short scale can have fat necks and skinny necks, scale doesn't effect neck shape. if you like skinny necks, pick-up an ibanez RG and see how you like it. Gibsons generally have fatter necks
