I haven't checked out the chart to see if they all can be bought in Ciao. I'm hoping they can. The sketch markers will not fit in the Marker Tower, but the Ciao will. I would really like to have the Copics in that tower.
I prefer the sketch, but inevibly there will be a color I want that is not available in Ciao. I'm to OCD to mix Sketch and Ciao
I could deal with Ciao in the tower, sketch for the other colors elsewhere.
