Welcome to FM, neighbor!
The answer to your question kind of depends on your uses for the lens(es).
I find the 24-70 f/2.8 to be too bulky/heavy to function as my walking-around lens; I love my 24-105 f/4L.
If I felt I needed to use a 24-70 f/2.8 frequently, I probably would have only that. As it is (I'm an avid hobbyist; I don't do portraits), my 24-105 f/4L lives on my 5D3, and my 28-70 f/2.8L lives in my bag, rarely getting used.
Given the good deal on the kit lens, and the used market price of about $800, there is little risk in getting the kit; sell the lens (for what you paid for it) if you don't like it.
