Do they all taste the same?

The point has been made on a thread about Kales that they all taste the same - so why grow several varieties when one will do? 
We know that a mix of varieties will extend the cropping season but, if we ignore that,.............my question is.......in your opinion which other vegetables or fruit "taste the same"? 

For me, its Leeks. There may be blue ones, yellow ones and green ones, some are early, some late, some overwinter, some crop in summer - but when it comes to eating them, they all taste the same.

Chard.

Sprouts. Definitely all taste the same. Carrots as well , I think. Lots of different shapes & colours. Taste the same.

But I still grow different varieties of both. Not to extend the season but because I like the different colours, shapes in my garden and on my plate.

Courgettes. Hoping to taste some this year!

Looking forward to that alphabet     

I hope you get a huge glut of courgettes this year 

I've been "thinking" - and I blame you and your mixed up tomato seeds. If all courgettes, say, taste the same, I may as well mix them up and sow them as "unknown" courgettes. It really only matters if I want to save seeds (and I wouldn't save courgette seeds anyhow) or, if one plant does particularly well and I'd like to grow it again./or badly and don't!
I'm always tempted by packets of mixed varieties (like Morton's Mix Lettuce) so I think I'll make up my own Mixes.
Courgettes, Leeks, Lettuce, Chard and some Kale.

Adding Radishes to the list1

Always happy to help   . 

This might be controversial but I’m throwing cabbage into the ring for tasting the same. Granted, white, red, savory & spring greens do taste different. But all the varieties of each of them taste the same .
