Which UGG boots are best to buy?

I am looking to buy new uggs. I already have short chesnut, but Im not sure which style or colour to pick next. I've been looking at the bailey on boots, and they look quite nice, but I have heard from people that they are not very good quality? I usually wear uggs with leggins. Should I stick with chesnut colour or different such as gray or chocolate? ah please help, Im so confused!!!
