V6 vs. Turbo

what is the potental of each engine, which is the better engine, I am leaning towards the V6 cause I like the body allot more, and I really don't want to bother with an engine swap, I'm looking at buying one of the 2, which one is better overall?

is their no insight onto this topic? I've herd that for tuning the Turbo is better but the V6 is a better stock engine, I would plan on hitting a goal of 250 to 300 hp, for which engine is this more attainable?
