Which tangs are more hardy???

I am thinking about getting some tangs for my 300 gallon.
Which of these fish are more prone to ich.
Blonde Naso
Purple tang
Yellow tang
Mimic tang
Sail-fin powder
Powder blue
Achilles tang

I know the Achilles and powder blue but not sure how hardy the others are.
they are all equal ich-magnets. The Achilles is the most challenging followed by the powder blue.
