Edited because my response didn't appear when I submitted it:
Normally the temperature for most recipes or cookbooks for cupcakes in Canada and the U.S is 350F which is 180C or in rare cases 325F which is 160F. Muffins are normally baked at between 400 and 425F which is 200 to 220C.
With decorated cupcakes in recent times people are trying to avoid any form of crown on top at all even though a crown is the natural result so they are allowing the batter to proof somewhat or rise while on the counter or underfulling the cupcakes to get a flatter top to them.
