My experience has always been the opposite -- better taste in-ground.
But, I think Worth is right, it is mainly an issue of "over-watering"
Out here, in our dry summers, it is very hard to keep tomatoes in containers alive without over-watering (because you need to soak your container tomatoes every day or they will dry out too much). And it is also easy to allow plants in the ground to grow under drier conditions. It doesn't rain in the summer, so there is no risk of over-watering by rain, and in ground tomatoes can be dried out well, without risk of killing them.
That said, I can see how in moister climates, it would be easier to keep tomatoes drier in containers with good drainage, and harder to control "over-watering" by summer rains.
