From the switches I have used, here is my preference:
Matias ALPS > MX Green > MX Brown > MX Red > MX Black
I absolutely loved the Matias ALPS switches, but for some reason, I had to get rid of the keyboard.
I really liked the QFS with MX Greens, but it was too noisy. My gf wanted to kill me (she always does..)
I had a Max Blackbird with MX Browns, but didn't like it. I think I might have been too quick to dismiss it because I thought the keys were too grindy. Maybe it required more breakin'.
I recently purchased a Poker II with MX Reds. I kept on reading Browns were simply dirty Reds. I bought into that and it was a mistake. Typing on Reds is boring to me.
I had a Deck 82 with MX Blacks and never liked it. I always thought it was a chore to type on.
So, I was still looking for that perfect keyboard.
I kept on reading Topre were the ****. Topre switches are the best. You depress on a key and can feel a small bump followed by a smooth actuation to a glorious mushy bottom. How could I resist? Plus the Type Heaven was on sale. I went for it.
And I got it today.
And I opened the box.
And I set the keyboard on my desk and I delicately depressed a switch to get the feeling of a Topre and......
..... f-word.
What is this ****?
For those saying it simply is a rubber dome keyboard, I have to say, I agree 100%.
I understand the "buttery feel". There is a smooth operation to them.
But... fun wise? A big fat zero. This is no ALPS or MX Green!!
Damn it. I figured, worst comes to shove, the keyboard would become my new work place keyboard. But it is so boring, I don't even know if I want to bring it at work.

Very, very disappointed.
And thinking it was either that keyboard or a Filco Brown...... but I had to know. Costs an arm and a leg to know Topre is hyper overrated.
I know people say you should give a couple of weeks to the keyboard before deciding, so this was my initial impressions.
I'll come back to it in a couple of days/weeks.
p.s.: damn... no way the keys are 45g. I don't have to press the space bar, I have to beat the space bar!
