I don't think you can really make that comparison. Of the PRs, 1.1 was really what 1.0 should have been. 1.2 did bring new features —*fair enough. But 1.3 is a patch release with really no new features. During my iPhone period we've received one major upgrade (iOS 4->5) and several patch releases. Another major upgrade coming soon. It's a different model, so I think it's difficult to claim N9 has been better supported. Particularly as no further major upgrades will be forthcoming and PR1.3 still has a bunch of pretty clear issues.
