Picking my favorite berry is hard, but I generally like a nice mix of sweet and sour or spicy. Salac Berries, Liechi Berries. Big two for me. Those go great in curries and stews. But, I know one berry I despise the most. And that's the Ganlon Berry. And I sometimes eat them since some of my Pokemon like Himiko love them. She says it has a 'refined palette' that I wouldn't understand. It tastes gross!
