Until I became aware of the 6-in-1s, my favorite was the Muir Glen organic tomatoes. For just about all my life, until I got to Texas and found that I could only grow tomatoes if I didn't leave home for more than a few days (during which my plants would suffer from the brutal Texas sun), I grew everything organically. I found the Muir Glen organic tomatoes, as well as their canned pizza sauce, to be far better than any of the other brands of canned tomatoes I had tried until then. I still like them, but when I got the 6-in-1s and compared them side-by-side with the Miir Glens, I personally liked the 6-in-1s better. I use them on just about all kinds of pizzas, and especially the deep-dish, where I like their simple, fresh flavor. I am also extremely fond of the San Marzanos, especially for the Neapolitan style pizzas, out of respect and admiration for the way things are done in Naples. I sometimes combine the San Marzanos with the 6-in-1s, also with good results.
One of the things I have learned in life is that there are no absolutes. That applies to everything, including tomato preferences, and the only absolute statement I can make is that there are no absolutes. That is why it is important to determine what you like, rather than rely on what others like or the experts say you should like. And not to be afraid to challenge what is held out to be conventional wisdom. Often conventional wisdom is wrong or at least suspect. Of late, I have seen this questioning quality in fellow member Cheesy and I admire it since it reminds me that there are no absolutes and that I should make up my own mind about things and not delegate that responsibility to others.
