I won't let the general feels of a single key press determine which switches I'm going with, I bought my Filco blind due to strong suggestion from this thread, after I got the keyboard, it was totally different from what I expected.
After I got my Poker 2, I noticed the differences of:
1. Build quality (Filco vs iKBC)
2. Plate mount vs PCB mount
3. Keycaps material and thickness
4. With and without O-ring
I think for those MKB sifu, there's plenty more of why they choose one over another, but I'll leave it for others to add to the list.
which is why general consensus is that Topre is king. If you have bought a Topre, it would have saved you so much headache and money and time effort (from having to buy/sell all the Mx boards)
