There are also huge regional differences. When I interned one summer in the Bay Area I was stunned by the quality of the fruit available in California. I realized that, coming from Massachusetts, I had literally never experienced ripe versions of these things before (avocados stand out prominently in my mind).

That’s not to say that we can’t get amazing fruit in Massachusetts, but the selection is quite different. Apples, blueberries, raspberries, and cranberries are all fantastic. Oranges, peaches, sweet cherries, avocados, and many other things are mediocre at best. Getting great in-season fruit and produce is the primary reason why I now have a very large garden, but I need to temper my expectations even for some of the things I grow. Outside of a farmer’s market, this is the ONLY way to get a decent tomato in Massachusetts.

Agreed that fruit selection is very region-dependent. I grew up in the great lakes area - and we had super juicy peaches every summer. I have yet to find ONE peach in California in 20 years that measured up. Even when they're "ripe" and somewhat juicy, the texture is still rough/coarse and severely lacking in flavor.
