I've used SeekingAlpha, Barrons, the WSJ and FT in the past.
SeekingAlpha has well researched articles and it has opened up my eyes to companies I wouldn't have considered otherwise. However, some writers may own shares in the companies they cover, and you'd need to take that in mind when you read their writings.
I like that the WSJ and the FT tend to have longer form articles about certain companies or industries that wouldn't get coverage otherwise. If I had to chose one, I'd chose the WSJ. I found some of their recent articles on NIO, Wizz Air and Southwest Airlines very well written.
Barrons isn't bad either for daily news, although I find their articles often lacking in depth. However, I strongly recommend Barrons' StreetWise podcast, which you can listen to for free.
