Tastiest variety of starwberry

Thank you for your question. I wonder if the berry you had in France was a Fraises Gariguette, "an old and much-loved French variety that produces sweet and aromatic fruits early in the season. Grow in full sun for the greatest depth of flavor"? Unfortunately, "tastiest" is a description that is personal taste, but you can peruse the varieties available in the Willamette Valley in this OSU Extension publication (pages 4 to 6), to see if any of these fit the bill for you. "Charm" looks much like Fraises Gariguette, but looks can be deceptive with berries. Good luck!
