Smiteless start has a whole range of advantages. You get to get your second buff earlier, which means you can gank earlier. It also means your second buff is a lot less likely to get stolen, since you will be claering it earlier and with smite up (this is part of the reason in my opinion that counterjunglers like Shyvana and Mundo have fallen out of favor).
