Reuters, AP, and USA Today are pretty straightforwardly factual. BBC is close. NBC is okay.
Wall Street Journal, New York Times, The Hill, and NPR are the next category down. They're more reliable than most outlets when it comes to getting the facts right, but they are somewhat selective in what they report on, and they present it with a bit of a slant. Reading/listening to just one of them will give you a biased picture (especially if you read the opinion pages), so it's best to cross-reference them.
Washington Post is something of an anomaly. It's still reliable for facts, but very very slanted in its presentation, so take it with a bushel of salt; if it's your only news source, you'll end up with a very narrow perspective.
That about does it for the major sources. Pretty much everything else is explicitly agenda-driven. While they often get the facts right, they should not be relied on for facts or analysis. Even the ones that do great investigative work are VERY slanted (Vox and The Intercept are great examples of this). The others are just abject partisan outrage factories. Some of them are straight up clickbait and fake news. If you can approach them with a VERY open mind, they can be good for getting a window into how certain worldviews work. Otherwise, it's best to get your news from other sources.
On TV, the only relatively unbiased major network is CSPAN. Avoid the big TV news networks -- Fox, CNN, MSNBC, etc. They are so shamelessly sensationalized and slanted that they're not worth watching. The BBC and NBC are the only possible exceptions. Al Jazeera and RT can be good for getting non-American perspectives, but remember that they are HIGHLY biased and somewhat agenda-driven.
