The vaccine is used a lot in places like the US.
Most children get it and have a miserable few days, but at its worst, chickenpox can kill. There are pros and cons to vaccination, there are pros and cons to catching the disease. However, the basic answer to your question is yes, chickenpox is more unpleasant than two injections.
I have very clear memories of the discomfort of childhood chickenpox. The only childhood inoculation I remember is polio, because they made me have that nasty sugar cube. (And then gave me another sugar cube as a "treat" afterwards...) So I don't think any jabs traumatised me as much as weeing over chickenpox spots which I had everywhere. Like passing cut glass, it was.
