Que mérito teneis!
How can we say qué mérito teneis .
Context. Two young mothers of 9 children each.

[JPablo]

Yo diría algo así como: “You are admirable [for having raised so many kids]” or “That says a lot of you”... mmmh... or “It’s really commendable what you have done”
Decir: “You are a worthy person/s” creo que también funcionaría... Pero veamos lo que nos dicen los nativos.
