In general, I break a chain once - to replace it. The only other time would be a derailleur swap. I used pins many times in the past and always felt happy with them. The last time I replace my 11sp chain on my Tarmac using the suppled quick link, it was a PITA compared to the pin. "Forcing" it to lock into place vs just screwing the pin in using the chain tool and breaking off that extra bit.
Maybe if I was a big "off the bike" chain cleaner the quick link would make more sense. Even now, with a quick link on my Tarmac's chain, I don't have the tool to open it. Easier/cheaper to break the chain and replace the pin. But again, I might be way off base with this as I do it so rarely - new chain ever 2-3 years.
