Thanks for posting your findings and results.
I have found out through my own experiments,if the tomatoes or etc do not taste decent out of the can,its not going to be any better on the pie.That is,unless you are skilled enough to add ingredients to change the flavor.Im not so I dont bother wasting my pizzas with lousy tasting products when I know there are better ones to start with.
I have mixed up a few sauces with not so great products,and still did not like it before and after the pie was done.
Sometimes a sauce or canned tomato product is good, yet a tiny bit bitter,and is easily fixed by adding sugar,salt,maybe straining some water or etc,but aside from that,if it doesnt taste decent enough,or very very bitter,I dont use it again.
Im still learning,so not trying to sound like I know it all.Far from it.Yet,the experiments paid off,and I now narrowed my sauces down to just a few canned products I can buy.It is amazing what a difference 2 different brand names can have,and yet they are simply tomatoes to begin with.
