My 2.
At the point NAND technology is nowadays, I don't think you should be reducing writes at the cost of potential data corruption...

Well, I do maintain backups of my personal data. Anything else (e.g. Slackware-current) can be reinstalled.

Backups are always good. But NAND is a lot more resilient than it used to be and can usually withstand 100s of TBs written, many will run into the PB range (my drive is rated for 700TBs and if I were to write 50GB/day, which I'm nowhere close to doing that, my drive would last me 38+ years before the NAND wears out). Getting rid of a journal that could prevent corruption to save on the little bit of writes to prolong the longevity even further than it already is just isn't worth it in my book.

But it is nice to have discussions so people can see both sides and make whatever decision is best for them. Discussions like these in the past is what led me to do all my research on SSDs and NAND.

This is a different case, but I use journaling on my FreeBSD install (UFS) and my SSDs are 3 years old but have a ton of life left when I run smartctl against them. Agree that SSD drive technology now has made them very reliable and long lasting.
