No, they're actually miserable and I strongly prefer toilet paper (yes, I have read all the comments about whether you'd use toilet paper if it touched any other part of your body, etc.) Most parts of the world literally just spray cold water at you; some of them also require you to aim. Toilet paper is a lot neater than this.
It's neater in its application, not neater at its result. As you (and the article) mention, there's no way I'd trust wiping off with toilet paper if I got some paint on my hands, even though it's simpler than washing.
While I don't completely disagree with the argument, I do think it is worth pointing out that your hands touch other people. People often live with sweaty armpits, which is obviously a lesser version of the problem, but I think still worth considering: we put up with things that go in covered, mostly hidden places.
Maybe I'm a bit extra in this, but I do have a mental bit for how clean my hands are. If I've just washed them, they're "clean" (clean enough to put in my mouth). If I've touched anything, or any person's hands, they aren't.
I mean hey, if you want to walk around like that by all means. Maybe it's my ancestral Muslim side coming out, but I just feel dirty without cleaning myself afterwards.
Also, the water isn't that cold, even in the dead of winter here in the north east. And if you can't aim from that close I'm not sure what to tell you!
Having used all three, the neatest system IMO is to everyday carry a spray bottle of 70% isopropanol. Beyond just convenient hand sanitizer, this lets your wet the paper so you can finish with 2-3 wet wipes (typ. 2x dry + 2x wet). If the paper's thin, double it over a couple more times if needed.
It breaks down like TP (because it is TP), so this won't create a 100+ ton 'fatberg' in the sewer like commercial wet wipes can do.[0]
