To be clear, I encourage everyone to eat huge amounts of dark green leafies every day, the healthiest food on the planet, but if you follow this advice (and you should!) then just choose any of the other wonderful greens. If you eat regular boring amounts of greens (like a serving a day) then it doesn’t matter which you choose. I continue to eat spinach, beet greens, and chard all the time. It’s just that you can overdo those three, so when I’m trying to hit my pound-a-day green leafy quota I personally do mostly kale, collards, and arugula, which also happen to have the added benefit of being cruciferocious!
