Here is FACT...
There are TWO manufacturers (root manufacturers, not re-branding) of 3PDT switches, which is what EHX and ALL manufacturers of true bypass pedals use (at least the ones who don't use relays). There are multiple brands, but all are manufactured in the same Chinese factory. Cliff, New Sensor (which is EHX's parent company), Fulltone, they all have branded switches, but all are made by the same company in China. The fact is that while 3pdt siwtches are common, 3pdt stomp switches are a specialty switch which is generally only used in musical effects, and as such only one company still makes them.
I'm a boutique builder, so there's your proof. We all source from the same barrel.
Incidentally, switch failure is a much less common occurence when people don't slam their foot down when switching. I'm not saying you are, just making a general observation. There is just no good reason to slam your foot down on a switch.
I can speak to the precentage failure point too. I probably only ship 20 to 30 units a year (All I do are custom one-offs), and I've only had 3 switches fail in 3 years. EHX, well, they have a WHOLE LOT MORE units out there, and thus, more broken switches. Bottom line is no matter how sturdy the switch, you are still stomping on it and it's still a mechanical part.
tactile switching in and of itself offers no more reliability solely on the switching itself. BUT with a Boss or Ibanez pedal, for example, even the hardest stomp won't send very much trauma at all to the tiny switch below, due to the the pedal's design where a large metal or plastic foot pedal is taking the brunt of impact and the metal frame stops the actuator short of pressing further than it should.
