T@b is great stuff (I drink both T@b and Diet Coke, as well as "Mexican" Coke (made with cane sugar) and Coke Classic (less often) on occasion.
T@b is harder to find where I live. Only some grocery stores carry it. Those Who Know have these places scoped out. I went to my local retailer on Memorial Day Weekend and someone else had beat me to it and cleaned off the shelf. I was able to get a few loose cans from the cooler, however, so I didn't return home empty-handed.
So you like the flavor of T@b better than the other diet Cokes? I know they’ve reintroduced it (or maybe they never quit making it) so it must have a following.
