Hello fellow FG player 
Which games are you playing?
Since you're claiming that they die around 100,000 presses, you've probably got one of the following problems:
* you're smashing on the keys so hard that you're slightly warping the mounting mechanism.
* your measurements are inaccurate
* you are extremely unlucky and have had nothing but defective switches
Topre switches are extremely durable, and regularly outlive their claimed keypress lifetime by nearly double. However..
You're probably not going to want to buy them. They are horrible for fighting games. Fight pads / OEM console controllers work well because the buttons have very short travel. The travel on a Topre switch is much longer and the tactile bump is much larger. Get a linear switch like Cherry MX red/black, or Matias. As you're probably aware, all of the sanwa / seimitsu switches in japanese arcades are linear, for the same reason. They also have much shorter travel than a Cherry MX or Matias switch, so you might want to just build your own array of those switches, if you need a lot of them.
you're overexaggerating and you don't realize switches don't realize switches makes less of a difference than what most noobs think. As player performance goes it makez zero difference. also have you realized you're talking about 1mm worth of a difference? You sound like one those ppl from razers PR department, trying to trick the noobs into thinking their 1 mm actuation difference will make a difference in gamer. The WORST part is, you actually believe it LOL. And trying to pass down misinformation down. sigh....
Well, I think to an extent you are right. The difference in performance advantage of a Razer green and Cherry MX blue switch is so minute that maybe only pros would be able to tell the difference ( or maybe all that green Razer is giving them introduces a bias

). Either way, that's not really what I'm talking about.
Having played fighting games for years, I've learned that if you want to be good at them (and not frustrate the hell out of yourself), you really need to be able to execute your combos consistently and on-demand. In some games that is no small feat.
Making it sound like you know anything about 1-frame links.
He's referring to a type of combo in many fighting games which requires you to press a button
0.016~ seconds after you pressed the first. These sort of combos are actually fundamental to the game and any good player needs to be able to perform them. There are some tricks you can use to make this
slightly easier such as priority linking, but in some cases you can't use that. In these types of situations, yes, the switch you're using really does matter. You need something light that you can just tap quickly and get on with it. I think fighting games are a great example because they rely quite a bit on the player having good reflexes. An RPG could be a counterexample.
Anyway, I think you're just underestimating the fine control and sensitivity that the human finger has. I think everyone can agree that scissor switches (laptop keyboards) have a huge difference in feel to a standard keyboard. Did you know that the difference in travel distance is only 2mm? If I was pressing the keys with my foot I probably wouldn't be able to tell, but the finger is a much more precise tool.
