What does "No worse a husband than the best of men;", Antony and Cleopatra, mean?

Answer 1

It means exactly what it says. There's no hidden code here. If you don't understand the words, consult a dictionary. 

Answer 2

He was up there with the best, obviously. 

Answer 3

Its in the sentence no worse that the best meaning up there with the best no less 

Answer 4

You need the full line -  "To make you brothers, and to knit your hearts with an unslipping knot, take Antony Octavia to his wife, whose beauty claims no worse a husband than the best of men, whose virtue and whose general graces speak that which none else can utter."  It simply means that Octavia is of such standing/beauty as to be able to marry the most eligible man available, which Agrippa is suggesting is Mark Antony.
