I just had to vote for Clone Commandos, because when i was younger i read the great Republic Commando book series and normally i dont read that much, but these books just were so amazing i couldnt stop reading

ARC TRooper they look way cooler but if this is a fight ..... i dont know

Personally I don't understand why Commandos are voted for more. They are only so good because of the level of gear they have. Commando's and ARC's have very similar training. But I feel ARC"s have the advantage of personally being trained by Jango Fett and Alpha-17. If they were on an even playing field with equal gear I feel an ARC (while not easily I may add but i'm confident the ARC) would come out on top.

Question is invalid.
Different roles being arbitrarily compared to see which is better.
Its like saying which is better, a hammer or a saw.
They are both important tools.

I believe Arc Troopers are shock-troops / heavies, while commandos are more multi-purpose. Again, that is a generalization. As different troopers had a variety of experiences. Refer to Karen Travis Clone Commando books (which are canon, despite what any Disney Representative F&$k says otherwise).

Damn political correctness. It used to be at worst James Cameron with very strong themes of his beliefs. Now, they beat you over the head with it.
