ELI5: Why are vegetables more consistent than fruits?

Everybody's had that awesome clementine that's sweet and juicy, and the one that's dry and a little sour.  Or the grapes that aren't as firm as they should be \(even sharing the same cluster as awesome grapes\).  Or the flavorless pineapple.  But broccoli is always just broccoli.  Asparagus can be skinnier or fatter but it's still asparagus.  It seems like it's more than just ripeness.  Why does the quality of fruit seem so much more inconsistent than that of vegetables?

Vegetables can be bred faster since most of them are annual plants (they grow and produce seeds every year). In contrast, many fruits come from trees that often take ~5-10 years before fruiting. Therefore, it is easier to select and breed vegetables for desirable traits.

For supermarket vegetables, the main properties you would want are that they look good and that they store longer. Taste is usually an afterthought. Therefore, supermarket vegetables taste consistently "meh".

If you do have the chance to grow your own vegetables or eat fresh from the farm, you will find that vegetables can also have variations in taste. But in general they taste much better than supermarket vegetables.
