I think the discrepancy lies how the companies take their level measurements.
If you put a level on the frame rail, then the Toytech 3/2 will be level. However, even with this lift, the 4Runner still has design cues that make it look like it has factory rake. Front fenders will still be lower than the rears, the window lines will slope down from the rear to the front, ect....
If you measure from the center of your hubs to the bottom of your fender, then the Eibach lift will give you an even measurement both front and back, making the truck appear level in stance.
