Yeah, you can usually count of Netflix having the biggest hits of the year and then a few other things, but if you have more niche interests they are kind of lacking.I'm big Gundam fan, but they have comparatively little compared to CR.
If you're somebody that's really into obscure isekais, or shojo stuff, or like 80s and 90s retro OVAs, Netflix is very lacking. They're essentially anime for the casual market, not the hardcore.
