> but Chrome sync in ICS seems bigger to me.

Not to mention full-fledged Firefox and Firefox Sync on most devices 2.1+

The problem for Apple is that adding browser sync to iCloud isn't enough. Most people aren't browsing with Safari on the desktop. That means unless Apple

(a) loosens up on third-party browsers (unlikely based on past behavior) and/or

(b) opens up sync APIs for third-party desktop browsers, including third-party browsers on Windows (possible, but at least somewhat uncharacteristic and potentially tricky technically),

Android is likely to maintain its edge in browser sync.

Of course the same logic suggests that browser sync to desktop IE is potentially an under-appreciated advantage for Microsoft and Windows Phone. That's blunted a bit because, based on Microsoft's previous announcements, new versions of IE (including, presumably, whatever version adds browser sync) aren't going to make it to XP, but that's still a significant universe of potential sync targets.
