bpizza,
I have sampled 6n1's and 7/11's side by side and to me the acid in the 7/11's tones down the sweetness and adds a nicer brightness. For something that is very similar in quality but a couple notches down on the sweetness scale I highly recommend you try Walmart Great Value crushed tomatoes (not kidding)...easy to find and ridiculously inexpensive for what you are getting. Good luck.
Bob
