BW man.. what is your current wpm.. and what do you find about certain keyboards that's actually limiting...
My current is 75-88 wpm and I use Qwerty.
When I started into mechanical keyboards I was 30-40 wpm in March.
Because I started with the BW obviously I have used it the most, but with each new acquisition I have put them through their paces by using them exclusively for a week.
What I find helps me is tactility which I equate to some cars steering being more responsive and resulting in better handling overall. So while I'm on fire I can do well on reds, this will not always be the case though because of the lack of tactile bump or click. Blues and greens have both. Between boards with the same switch, such as the ducky and steelseries I find the limiting factor mainly to be the placement of the right shift with the 6gV2. But this can be negated with sticky keys.
With the Das and BW the BW is more crisp for some reason. But there must be other factors I am not aware of in the construction of the two boards that make them sound, feel and perform differently. That is why I liked the idea of at the next convention or meetup having cardboard boxes with cutouts and having numbers of good typists try out the different boards and then tallying up the results.
Some people are obviously so well trained in their muscle memory that they do not require tactility. They are like robots each finger moving to the right spot at warp speed and not deviating too far from home row to achieve good accuracy and may type fastest on reds on average.
My results are skewed by the fact that I used certain boards earlier on in my gaining more typing skill so I should maybe try all on the same day and test. I could do so blind folded, and see how many lines of "the quick brown fox jumps over the lazy dog" I could type perfectly each and with perfect accuracy.
Other people may weigh in on the factors that make different boards even with the exact same switch from the exact same batch more tactile, smooth, etc. These factors may of course include keycap material, type of switch and switch design (alps, topre, mx, or buckling spring), switch mounting, clicky or non-clicky, distance to actuation point and distance to bottoming out, reset point, case construction and flex.
Don't ask me but I can pick up the Matias Mini or unicomp and get 72% fluidity score on klavaro right now but with the topre maybe only after 10 tries. I think the topre while feeling tactile isn't really tactile in that it is not conducive to typing fluidly. You may ask what is conducive to typing fluidly? Tactility eg. audible click and actuation bump; however, while the matias is quiet it is still tactile enough for fluidity. How can you test fluidity? With a metronome. Or using the built in measure in Klavaro.
