I generally don't use aggregator sites.

I scan/read ~20 journalistic websites each morning. In the modern meaning of "journalism", obviously these sites are also publishing news from elsewhere, but they also have their own staff, and generate original articles.

The usual ones: Wash Post, NY Times, Guardian, El Pais, Asahi Shimbun. But also a number of local news sites: San Diego Union, LA Times, San Jose Mercury, SFGate (aggregator?). I used to have tabs for Ars Technica and El Reg, but now I only open those in response to a specific article.

Probably the only true aggregator I use, is HN. Which I monitor via the ##hntop IRC channel on libera.chat.

I also subscribe to RSS feeds from about a dozen blag sites.
