We really like Publix, its a great shopping experience. Terrific Bakery, good meats. However it is not our main "go to" supermarket as, as one would expect, everything has a price. So yes, when you want that special item, you cant normally go wrong, also things like Publix Ice Cream is a great product.
This might be a local issue to our area in South Carolina, we have three Publix within a reasonable driving range and lately have been a bit more turned off. I wonder if they are expanding and losing control of quality or not.
We are pretty big on fruits and vegetables, Publix puts on a nice display but in the last year we found ourself paying a premium price for a subpar product and have found our local sloppy Walmart super center (and sams club at times) has had far superior (and fresh) fruit and vegetables, you would expect at the cheap prices for it to be inferior but its superior and that was the day I started turning sour (no pun intended) on Publix, numerous times we bought garbage tasting fruit from Publix, we even returned it once.
