"The one he had is not bad; mine is better."

Translation: Celle qu'il a eue n'est pas mal, la mienne est mieux.

I typed this and it was accepted:

"celui qu'il a eu n'est pas mauvais, le mien est meilleur"

But the answer has mieux, not meilleur, so I was surprised that my answer was accepted. Which is correct?

Both are actually correct. "... le mien est meilleur" says that I have a better (adjective) one; "...le mien est mieux" says that mine is better (adverb) [than yours].

I think it's because you used masculine words (celui, eu, mauvais, le mien) instead of feminine words (celle, eue, mauvaise, la mienne)

[Babette655656]

Could we also use the word "meilleur" instead of mieux?

I would have thought that "Ce qu'il a eu n'est pas mal, le mien est mieux" were the masculine version of Duo's translation, but it was not accepted. Where did I go wrong, or should I report ?

"Celui qu'il a eu..." -- otherwise perfect!

Why "il a eu" and not "il avait"?
