I have the aluminium set, which look like SW motec but have the Suzuki name stamped on them. The plastic set could well be made by Givi . If you take the aluminium top box, the frame needs an extra strengthening bar which the plastic top box does not require. Some after market aluminium top boxes do not provide this bar, which according to Suzuki is required due to the extra weight of the top box. ( a bit of a mine field). The Suzuki aluminium boxes are very well made.
