I've been smoked grappling by women grapplers in class before. (And I wouldn't have a problem getting smoked in competition by one, either.) But I don't think they should ever compete against each other, even in the same weight class.
And I tell, ya, I've been around a lot of guys from Brazil. Can't even imagine them allowing women and men competing.
Not allowing women to compete with men only holds womens leagues back. They have nobody to compete with and the standard is generally worse.
