Sorry, but I'm going to make a quick short review as this is my first Filco and first Cherry kb.
Construction
My first impression was, "damn, everyone was right, it's heavier than it looks". The board feels very sturdy, doesn't move on the desk and doesn't flex much at all.
Cherry Blue MX Switches
Before now, I had only seen youtube videos and listened to a few clips, but the blue cherries are louder than I imagined. The force required for a keystroke seems greater than I'm used to (HHKB) and I'm sure I'll adjust to it in a week. I briefly compared my skills on the HHKB and my untrained skills on the Filco. I feel much faster on the HHKB, but I'm sure some of the difference is because I'm not familiar with the Filco yet.
Keycaps
I was interested in the new Otaku version being re-released and was on the fence, but as soon as I read in the email about a white version, I pounced.
The keycaps feel smoother/slicker than I was expecting. Yes, the spacebar will go shiny soon, but hopefully the white/cream keycaps disguises the wear. I think these are the perfect shade of off-white and I imagine this board will look good for a long time. Luckily, I keep my computer in a darker room and I'm not much of a Cheetos fan. I would prefer that the function keys be a darker shade, but mainly I wanted white keys for cosmetic reasons. I briefly compared the HHKB and the Filco to a white sheet of paper to find the Filco is a creamier white than that of the HHKB.
LEDs
I haven't seen any other Filcos to compare to, but they look fine to me and I still have my retinas.
Red Esc Key / WASD Keys
ehh, I have a topre red esc key that kinda set the standard, so....I probably won't use the Filco one, I'll just keep it in the box. Also... the red esc key on any board is not my style. The WASD keys were ok, but again, I'm not putting them on, just wanted to have them for bragging rights.
Overall
I'm thrilled with this keyboard and would definitely purchase another Filco board when the time/need comes. Will it replace my HHKB? Probably not, They are two different boards. The HHKB feels more natural, is a thousand times cooler looking and plays well with OSX. Honestly though, after seeing what I can get for 121 dollars, the HHKB is looking a little overpriced.
