Did you actually try the Sony’s? That (rain activating touch) doesn’t happen. You can’t take your experience with a completely different product as universal truth.
My biggest issue with touch control is the user experience. That is, when it works flawlessly it's as good as physical buttons, but I rarely experience the same level of reliability with touch as with buttons.
If you have the Sony's and you're happy with them, then good for you. They're good headphones, just not the best ones for me.
