I am debating between FUT and FUE techniques for hair transplant

I am debating between FUT and FUE techniques for hair transplant.  I am fairly young and hair loss is not too extensive at this point.  With what I can gather, this means I am more likely to need an additional procedure in the future.  When you have a second procedure does this mean you also have an additional scar?  This might help make the decision between the two techniques.
