Sentence case looks a lot better to me, but that might be a cultural thing. I think title case is a lot more common in the US compared to the UK.
I see no need for title case though. Headlines stand out by design, they don't need to be 'Shouted at Me' too. I'd only use title case if I were writing for a site like TMZ or Gawker or something else where you need to pretend like you're 'real' news by copying the trappings, like some kind of cargo cult.
