Should i get ugg or coach boots?

should i get these...http://www.amazon.com/dp/B001QT9TSI/ref=asc_df_B001QT9TSI755547/?tag=shopzilla_rev_1398-20&linkCode=asn or uggs if im getting both for about the same price. It would def look tacky with a coach bag, but i dont have one, so its ok. but, what age would this be appropriate for?? Are the coach boots more leaning towards women, while uggs towards teens. im in high school, which ones should i get>?
