I'm not talking about disease resistance - carefully selected root stocks will usually have the advantage there - but if the tree is capable of developing a tap root from seed it may be able to grow deeper into the soil to find soil moisture and nutrients. My understanding from reading is that grafted, bareroot and container trees almost never re-develop a strong tap root.
