News360 is the top of the line for news readers on WP8. Bar None.
AP app gets an honorable mention. Mainly because I just got my hands on it and my initial assessment of it says that with the exception of the ad box at the bottom, which I hate, it ain't half bad. But its early yet.
I like MSN app too. Its great when I'm in the mood for light reading.
AppyGeek was trying to be awesome at one time. Now it starts and crashes. Still not bad on Windows 8 but on my L920, not so much anymore.
Sports news. ESPN Hub. Its just good.
Newser has my attention. Just not my time yet. It feels like a good port to me but I'm keeping it. I think they have some surprises to come
Collector is the most promising news reader I've tried. I like the lay out and the design but the fetch could be snappier. Seems the app should prefetch the article but it doesn't. There is a delay to bringing the article up to read it. Its probably just a maturity thing but if they could fix that, it would be awesome.
One other app I do like quite a lot is The Verge by MasterDevs. (don't accept imitations of this app) Now THESE boys got skills. They could blow out a majority of newsreader apps if they would apply what they do to a pure newsreader. Prefetch is lightning fast and the layout is easy peasy. I'm hoping MasterDev's would hook up with what Bing is offering in its latest update to the desktop. A Bing newsreader app like that on my phone would be the bomb.
