I haven't taken them apart yet but both are very decent... My new style 3D Super 1W has an RYAK which is, very very nice... Though both my Metal Gears are nice on their own, when compared against each other, one is less green and slightly brighter than the other and that one looks a LOT like the RYAK. The other is probably an RX1* by my guess.
Both both of my Sam's Elements are brighter and more intense than the Metal Gear... is the Metal Gear slightly resistored or something? Maybe the Sam's are just using lower Vf LEDs because they are both brighter than my brightest Metal Gear.
