I'll let others chime in, but I believe Powder Blues are considered a little hardier compared to Browns. Then again, Blues are also known to more aggressive than Browns.
I was thinking just the opposite. Either way, I wouldn't classify either as "hardy" and would look into other species if that is a trait you are seeking.

When adapted after good qt both would be similar in hardness. But it is easier to find japonicus powder brown speciemens that adapt faster to aquarium conditions...
