There are two reviews of the new white Leos
here and
here. Reaper's has some excellent pictures.
This is my first time trying authentic red switches. I've had a ghetto red board for some time though, and so far at least I cannot tell them apart by feel. Like many here, I'm in love with the red switches. Such a pleasant yet utterly different experience from blues. In terms of aesthetics, I really like the off-white color of the board and its lasered keycaps. The Leo niceties of a detachable cable and channels are a step above the Filco.
That said, I really do like the angular edges of the Filco much better than the rounder Leo. I'm not sure what the Filco's body is made out of, but I also much prefer its matte look to the Leo's semi-shiny plastic. It just makes the Filco feel like a more expensive piece of equipment.
edit: The stabilized keys are sqeaking like banshees. I'll have to get some grease. And it might be my imagination, but the real reds feel a touch lighter to me than my ghetto reds.
