Br- is far better leaving group than Hydroxide ion this is because Bromide ion is more stable than Hydroxide ion which is because charge density of Bromide ion is smaller than the charge density of Hydroxide ion since Bromide is bigger in size then hydroxide ion so charge density of former would be lesser than later making it more stable consequently, its existence as a so-called  free ion is more easy then Hydroxide ion, so is a better leaving group.
