I have used Slackware64-current ever since it was released. Any problems I've encountered have been minor and easily fixed. 99% of those were PEBKAC errors. I had been a bit busy lately and had not updated for almost two months. I kept putting it off, and then all of a sudden the update was pretty massive. Thanks to a tip from markush, I set slackpkg.conf to download all before installation and I had zero problems. Even without that, I always update the local mirror first, so I still would have easily survived the network problem.
I used Arch for almost a month about a year ago. Arch has almost daily things to tinker with. I am getting old and too lazy to tinker every day. The Arch Wiki is definitely impeccable. 99.99% of the answers to problems can be found there. That Wiki kept my Arch install running.
I am absolutely not a Linux guru, but I do consider myself a competent Linux user. So one day while researching an update fix on the Arch Wiki, I asked myself - "Why do you want to run a system with so many documented problems?". The answer was that I didn't. That answer is also a testament to my own laziness, and not a fault of Arch.
So I killed the Arch VM, and since I had nothing pressing to do in -current, I took a nap!
