Partially thawed berries are good for eating straight. When fully thawed, the berries will break down to some extent and lose juices. Thaw in refrigerator with a dish to catch juices. The thawed berries are fine for purees or in cooked dishes. If you are cooking the berries, you may skip the thawing depending on the dish. Good Midwest berries handled this way will beat anything from California fresh or frozen.
I remember an episode of Alton Brown's "Good Eats" where he explained the best way to freeze strawberries. He said that the slow freezing process of the normal household freezer will produce ice crystals which will shred the cell walls of the berries. This produces watery, soupy results when thawed.
His solution was to use dry ice. He packed the strawberries directly in dry ice in a cooler for 30 minutes. They came out as hard as a rock and he promptly moved them to freezer bags and into his freezer. He said that the faster freezing method of the dry ice prevents any crystals from forming, leaving the cellular walls of the berries in-tact.
