Welcome to the board Mr. Koz and glad you decided to post your thoughts.
For more flavor you may want to try a home made cooked sauce rather than a pre-made or uncooked sauce. It is difficult to get that perfectly balanced oregano taste from a sauce. I've been trying for years to get one with the correct balance, not for just oregano but for the correct blend of all spices. Unlike our member Duckjob, I've been satisfied with the dough and it's the sauce I'm constantly tweaking.
If you like that chain pizza shop type taste, one of the things to watch out for is that you're not spreading the sauce on the dough too thick. Most chains are kind of skimpy on the sauce, such as pizza hut. In fact, a copycat pizza hut recipe on the net that's been floating around for years, states that one should use a can of tomato soup as the base for the sauce. While I don't suggest this, I think the thing to be gleaned from that recipe is that the sauce is thin, aka watery. Pizza hut sauce is rather bland to my taste buds however.
For a robust home made tasting sauce, you may want to try the "Lentini sauce" I've posted elsewhere here a few weeks back. It has a traditional old world Italian taste, which I liked growing up but doesn't do much for me today.
To get your perfect sauce, I would suggest starting with a 28oz. can of the Stanislaus and just set up 5 or 6 tupperware containers. Fill them all with some of the stan sauce and try differing amounts of spices in the containers until you pinpoint which amount of oregano pleases your palate. Once you get the oregano down, you can build off of that, taking one spice at a time to get where you want to go. This can be quite time consuming but a lot can be learned from this method. Once you get spice quantities perfected, then move on to overnight refrigeration and it's effects, then cooking of the sauce and it's effects. Then, move on to differing amounts of moisture and how thick versus thin spreading onto the crust effects things. This is the route I'm starting to take with the Stan full red I just bought. Sometimes you have to start at ground zero to really get what YOU want.
