News Fuse and News Addict appear to be just collections of bookmarks with some added graphics.
Fluent News can be read entirely offline, comes from multiple sources, and collects stories in one place rather than repeating the same story from different sources. I like downloading the news in the morning or afternoon and then reading them offline later (it still connects to get new stories, and I've requested automatic sync as an option rather than the preset upon opening the app). But if you've already downloaded most of the stories, updating usually takes little time, only if net connection is spotty and slow does it take a while.
