I always wanted MAC lipsticks when I was younger and I still get so excited every time I buy one. Every shade and finish I've tried has been consistently good. Probably the best bullet lipsticks I've tried in terms of longevity, smoothness and pigmentation. The shade range is amazing, they have every shade and finish I can think of. The packaging is sleek and simple and looks so good.
I think there definitely are cheaper alternatives that are still excellent and dupes but I recommend these highly. I've loved every lipstick from MAC I've bought and get so much use out of them.
