I tend to avoid using switch/case for quite irrational reasons. The break statement just looks wrong and I can't layout the code in a way I find at all pleasing. I'll almost always use a sequence of else if conditions instead.

In my ideal world, it'd look like...

    switch (x)
    {
        case 1:
        {
            /* ... */
        }
        case 2:
        case 3:
        {
            /* ... */
        }
    }

And before anyone points it out, switch is the same as else if when the thing being compared is a simple local variable.
