Best Tasting Swiss Chard

[TC_Manhattan]

I want to grow Swiss Chard for the first time, and there are so many varieties to try.

Which do you prefer (and why)?

Oriole, Five Color Australian Chard, and Bright Lights are varieties that caught my eye,
but is there much difference? I am zone 6, with a few weeks of hot 90 temps in July, and bloody cold for a few weeks in winter.

Taste/flavor are also considerations. Any opinions, information, recommendations are greatly appreciated. Thanks!
