I'll give it you straight up. The restaurant store is awful. Restaurant Depot is awesome, and I've never even been there. I'm just basing that on what other people have said, and also what I see on their website. The restaurant store carries a lot of equipment, but not so much on the flour and sauce side.
I bought a pizza paddle there recently, and had to buy a more expensive heavy one, because the one I really wanted was garbage. The quality of many of the basic paddles was really poor. A lot of them were warped, or the wood was wet, or both. I have a 12 inch long handled one that appears to be either maple or maybe parawood. It's very nice. All of the larger sizes they had in that style appeared to be cheap pine. I also find the store to be dark, and sometimes difficult to navigate, and their prices don't seem that great.
On the tomatoes, I think I wanted to originally try tomato magic, until I read the descriptions of the Stanislaus products. Then I settled on the full red no basil. I tried 6 in 1's once. They were good for what they were. The sauce I ended up with tasted very much like Hungry Howies, which is an American chain. Their sauce is sweeter and less spiced than other chain pizza's. It's a good sauce, but it's not a Jersey Shore pizza sauce. So, 6 n 1's are out for me.
Lately I've been using SM's straight from the can, with fresh basil, dried garlic, and chunks of fresh mozz. That's a fantastic pie.
