I'll also add that the 10 roll also gaurantees a servant. While I don't know exactly how the math is factored into this, it basically means that the 2 gauranteed slots have a greater chance to get Illya than generic rolls. If you remove all CEs from the equation, there's a higher chance to get a gold servant than if you could get CEs. If you remove all silver cards from the equation, there's also a higher chance of a gold servant. So overall, this makes for a reasonably higher mathetmatical yield than single rolls. It does come down to taste but straight math says that 10 rolls will be better.
