They are all great. But keep in mind the chroma does NOT use Cherry MX keys... it uses the razer "Green keys".
Pick whichever fits your budget and aesthetic preference.
Have you researched which Cherry MX keys you prefer?
Which cherry MX key is the best? I was thinking red
There is no "best". It's entirely up to preference, I personally hate any and all mechanical keys. I prefer rubber.
You really should find a way to test different keys before you buy a keyboard, especially in that price range.
Is there is a microcenter or other computer store within driving distance of you? I know microcenter has mechancial keyboard displays that offer the different keys like brown/red/blue etc
But if that's not an option, any computer store will let you open up the box and test it out
