Which share icon is most appropriate for web?

Now days there are multiple viable share icons available, but they are mostly mobile OS specific (iOS, WP, Android...). I wonder which icon should I use for the web that most of the users would recognize?

Has anyone done any A/B tests on how users respond to different ones?

Its a simple album page where you can get links for each album/image and then share it with a friend, nothing special, just popup on click of an icon.
