Good points. Yes, these comments truly prove that "Your mileage may vary".
The grass isn't always greener, and with so many users, our personal experiences are simply "statistical anomalies / anecdotes" to the other guy, but are 100% our relevant personal experience to ourselves.
It kind of reminds me of my uncle who does surgery on backs. When a patient asks him, "What's the success % rate on this surgery?" He replies, "100% or 0% for YOU". It irked me to hear that from him, as an engineer, but he's so damn right when it comes to personal experiences & preparations (emotionally & otherwise)
