I suspect it depend on what purpose you are using the keyboard, and to a much larger degree to the amount of experience one has with one type of keyboard. To make a analogy, a professional car racer is likely to have a strong opinion on the sound of the car engine, the behavior of the car and how much pressure is needed to turn the wheel. What would happen if you put a race driver in a car with noise cancellation so they can't hear anything, change the turning strength of the wheel so you need a fraction of the strength, and removed any "tactile feel" from the car (increased suspensions and so on). I would suspect that in the short time their racing ability would drastically drop, and possible long term. Hearing and feel are very core senses and gives ques to muscle memory, and it make some sense that cutting them off would likely harm performance in a competitive environment. Personally I know that when I go and type on a membrane keyboard I tend to type with more mistakes, hammering the keys way too hard and have to look down more often at my hands. I suspect that 90% of that is down to muscle memory, but I am yet to be convinced that it is 100%.
