I would take a wild guess and say the only reason the 10-22 I s leading by such a wide margin over the 10-18, is because the 10-22 voters own one, and have never shot a 10-18. I had a 10-22 for eight years, great lens. I decided to get a complete STM lens kit for my T6s. The 10-22mm went to my brother.
Heya,
It's a preference thing. The 10-22 is older, sure. The 10-18 has slightly better optics (very slightly), and IS. AF is meaningless on these lenses really, so that's not something I'd even care to compare (STM vs USM). The key difference is the flare performance. The 10-18 does ok, but the 10-22 does better at flare handling. It's that simple. The 10-18 is cheaper new, overall has great performance for it's cost, and is a good bargain lens. But it all comes down to what you put emphasis on. In an ultrawide, my number one priority is flare performance, my second priority is normal filter use (no bulbous fronts that cannot take normal threaded filters), and my third priority is corner sharpness when stopped down a bit. After that, the rest is just whatever to me (AF, IS, etc). I do care however about how light sources (light spikes) render at narrow apertures (F16, F22), but not nearly as much as how an ultrawide handles flare. And the 10-22 simply handles flare better.
Very best,
