Quick question about Copics

I've been looking into getting some Copics & have a quick question for all you experts out there: is there a big difference in quality between the Sketch markers & Ciao? The Ciao markers are a couple dollars cheaper & they're already kinda pricey so I'd prefer to stay with those but wasn't sure if that would be a mistake.

Or, if you've only tried one type of Copic I'd really take any hints or tips you can give about using them. The tutorials are helpful but sometimes there are little quirks, ya know? I'm looking for all the help I can get! So if you're familiar with Copics I'd really love your input!! Thanks in advance :)
