If Plato's republic is not the best form of government, which of his contemporaries has a "better" option or a valid criticism?

I'll preface this by saying that this IS for school work, but it's actually a question that I'm genuinely interested in. I'm meant to discuss whether or not I believe that Plato's Republic is the greatest form of government. 

I disagree, mainly on the basis that unchecked rule by a Philosopher King is the purist form of aristocracy and would lead to the issues that Plato is attempting to "fix". 

I'm meant to cite from the following to aid in my argument: **Aristotle; Polybius; Cicero; Epicurus; Any**   
**relevant Federalist Paper ; any work of John Adams; any work of Thomas Jefferson.**

So, I guess, the purist form of my question is the following: Which of the above listed writers/philosophers has an argument against Plato's Republic and where can it be found?

Thank you in advance for your help!

This is a bold but perhaps under-motivated use of the word "contemporaries!" In any case, this is not a question with a right answer. Your job is just to make an argument about these things as they seem to you. Do any of those people have arguments against Plato? They do if you think you can articulate one! Where can it be found? That's up to you! All of those writers had quite a bit to say about government in many of their works, and so you can pick pretty much any of their political philosophical texts and find things relevant to Plato.
