It's really not that bad. CrunchyRoll has _almost_ everything, especially since Sony bought Funimation and AOD shut down. Some of the real Blockbusters miss sometimes (Oshi no ko, Cyberpunk, Pluto, etc.) because those are the ones that are worth it for Netflix, Amazon and Disney+. CR is great for someone watching a lot of anime. If you want to watch the one or two big shows each season you might not find them there though. I rarely find anything I can't watch in Japanese with english subtitles.

(Old stuff is often missing too. if you're after that those I understand what you mean.)
