They're both correct. Both ways indicate a negative 2 charge.

I think 2- is used more often especially when for the chemical formulas but if you're drawing a Lewis structure and you're just labeling the charge on the side I don't think it matters too much.

The standard nomenclature for writing the charge of an ion says to follow the number with the sign i.e. 2+

I'm pretty sure it matters which way you say it and they can't be rude interchangeably but I might be wrong...
