I didn't know there was a v2. I believe the one I shot (rental) was a v1. I found I could shoot it pretty well, but the boxier grip of the XDs fit my XL hands much better. I liked the G43 better, as well.
From watching a gazillion videos on the topic, I get the impression the Shield is the most popular of the ultra-compact 9mms, with the possible exception of the Glock 43. Then again, the Shield is also very price-competitive, so that might explain it.
