Just completed the update. So far, so good.
Some minor (but nice) visual enhancements, speed is at least as good as before, nothing to complain about but nothing groundbreaking (but nobody was expecting that from 4.3).
Can't post a screeshot right now but baseband is mk5 and kernel is 3.0.31-2140838
I updated with kies and I'm with Rogers.
I haven't done a factory reset (like I usually do after a major update) but the responsiveness of my phone makes me believe it may not be necessary. Time will tell.
Hp iPaq 6955 -> Samsung i780 -> Samsung Captivate -> Samsung Galaxy S3 -> LG G2 + Nexus 10 (32)
