I purchased an XM and Ushio 10K 400 watt pretty much at the same time almost a year ago. I would have to agree with you. The XM was brighter and whiter and now that the bulbs are near the end of their useful period I would say the XM is still better. Based on experience and price, I would prefer the XM over the Ushio
