For me, I don't need the extra frets, but what I like about them is it pushes all the other frets a little more away from my body, so playing stuff at the 12th fret is much more comfortable in my world. And I must say, on the rare occasion I am in the 20+ fret range, it is easier for me to see/know where I am when it is the same number of frets on the other half of the guitar ;~))
