I'd always trusted the NYT because their standards are quite high. They don't print extreme pieces or reporters who are dramatically L or R outside of the editorial and opinion paged so you know what's what is legit. Also, WaPo, in spite of many writers with a left-leaning slant because they also have right leaning writers too, on the editorial and opinion pages like the NYT.

Great media outlets have writers whom it is often difficult to really be sure what their slant actually is, particularly in the straight news departmens. So not being certain which writers are which lends itself to feeling confident that I'm not getting snowed by the writer.

Even those whom I know their slant are not extreme and don't play loose with facts.

Still, if you want to be certain that you are getting the entire scoop, sans any slanted opinions, go with Reuters and The A.P.
