SG hands down...
I have a V and an SG and the V gets five times the playing time that I spend on the SG. No problem playing it sitting down classical style.As an owner of two V's so far, I say pick the SG, unless you can truly commit to the V body shape. Otherwise, it probably will not get enough playing time to justify the purchase.
My V came with the Duncan '59/JB combination.I have a V, and I would totally prefer an SG. V's dont have the greatest pickups.
