I was looking for an Aeron B with Posturefit ($120 aftermarket) and swivel armrests (with tab adjusters rather than the gears; gears mean the chair is pre-2005). That combination isn't that easy to find in the used market. I was also looking for something closer to the $400 end rather than the $600 end. I'm not sure if the Leap V2 is actually better than the Aeron but for what I paid for it ($300), it had the armrests and the lumbar support that I was looking for, so I went with it. Aesthetically, the Aeron looks way cooler -- the Leap V2 looks like any other office chair.
