YouTube - tons of YouTubers who are independent, X - raw, fast, first hand news, Not saying don't go to mainstream news, just know the bias they may have.
Also make sure you take those same youtubers as what they are; raw, independent, and with less accountability than larger platforms insofaras accuracy of content. That isn't to say a smaller creators/channels are bad or not worth while, but being aware of context as you consume is important. We've unfortunately stopped caring about accuracy or accountability in many instances.
So for YouTube I haven't been able to find quality reporting for the most part (outside of an occasional niche issue).
For X my experience is that it's essentially impossible for me to vet personal accounts that people have. Also it runs into the issue where everything is just anecdotal so it's easy to get an inaccurate picture from that sort of information. This is without even getting into the huge problem with bots and even state level disinfo on X (and social media in general). Not that I don't use it at all, it's just not trustworthy or accurate for most things.
Edit: not that "mainstream media" doesn't have some of these issues. It's just not as bad as some of these other sources and it's much easier to get a sense for specific organizations than trying to understand the bias and veracity of a myriad of YouTubers and random people on X. Like it's much easier to understand the biases and issues of Reuters than a bunch of YouTubers and random people on X so for basic information I will go to places like Reuters first.
Edit2: for issues with YouTubers you have to remember they make money through engagement (and real news is less engaging). I think this is a lot of what's killed traditional media so I doubt YouTube, which is if anything more tied to this, is unlikely to be better. Then also look at the recent Tenet Media scandal. Like yeah I get some news from YouTubers but it's a real minefield when it comes to good information.
