To build upon what I said, I loved the way the armor looked in the original Alpha ARC's in the comic. Other than having a pauldron and kama, you could see visible differences in their experimental armor, RF's etc. Plus, the introduced of the Westar M-5 blaster was really cool.
I really dig the way the ARC's look in TCW as well. Again, you see a visibally different armor and set up. Now, it's dissappointing to see how easily they all came down in the Battle of Kamino, especially since they've been built up to near Godly status in the EU. But, they still looked awesome.
