I am no antenna expert...


but from what I've read in some of the standard antenna texts, quarter-wave
slopers are notoriously difficult to match.  I also believe by going to a
quarter-wave, you now become much more dependent on a good ground/radial
system then you were with the V which is essentially a dipole.

I will leave that question to folks who really know what they are talking
about!  :)
