Simply describing a strength without directly juxstaposing it to a competitor is a much better tactic. Let people use that as a reason to do a little research and draw their own conclusions.
Or just use the "problem" as a spring board, like so:
Neutral news
"MtGox is having trouble blalalalalalalabla"
Then
Positive news
"In other news, Nxt has just moved forward with the announcement of BCNext's second stage of Nxt. This will allow blablablabla."
People forget neutral and remember positive, also because it's at the end of the article.
People remember negative and it's harder to get them to the positive, while also looking like a plug.
In both cases Nxt comes out tops, but it doesn't look (in fact, it isn't) an attack.
I was thinking of doing this on my blog, but it's not aimed at providing news on BTC, and I don't want to take on that extra work
