Bullet construction will matter more than either on most cases. A bullet that will retain most of its weight while expanding reliably (like an Accubond or Barnes TTSX) will penetrate better than a traditional cup and core bullet (Rem Cor-Lok, Hornady Interlock, etc). For whitetails, either is sufficient honestly, unless you try to take a steeply quartering shot where you may need a lot of penetration to reach the vitals.
Like Jeffro said, either of those will work just fine for whitetails. Personally I like medium weight bullets that retain most or all of their mass.
