My first Cherry MX board was a Filco TKL with blacks. I thought I liked blacks the best for a while, but once I started using browns, I decided I liked the lighter springs better. I don't care for blues, but browns and reds are my favorites, now. Luckily, with the Poker, you can change the switch stems and springs very easily.
If you want a Poker, it's probably best to get one now. It's been rumored that Vortex will stop production of the Poker in favor of the Pure. With the supplies of Pokers coming from China being what they have been, I now believe this to be true. You can still find Pokers with black switches in stock in some channels, as they are a less popular switch type. The only new Pokers I have seen coming from China have brown switches.
