> But it’s a different variety. NH and ME blueberries and strawberries are best in my subjective opinion

Possibly. But it may be due more to freshness. Often fruit crops are picked before they're ripe so they'll ship better and then artificially ripened with ethylene gas and the like.

Eating NH fruit in NH means they were likely allowed to ripen naturally, hence the better flavor. When I travelled to Georgia and had a peach from a road-side farm stand I couldn't buy peaches from the grocery store any longer; only tree-ripened peaches for me from then on.
