The Clone Wars is superior to Rebels in almost every way conceivable. I was more sympathetic towards the characters in Clone Wars as opposed to the characters in Rebels. Plus, Not only that, Most characters in CWs were better created. The episodes were composed better than Rebels. The one problem I encountered in CWs is that one of the most hated, I mean "beloved" character in the Star Wars universe is present. I don't even need to tell you who he is as it is obvious.
The clone wars is better because they were building up to make the rebels and to show what took place between episodes 2-3 and they were almost done until Disney took over and made rebels just trashing the clone wars series and ignoring that most people hate the rebels and prefer the clone wars
