Best in terms of content, variety and quality? Not really. They're often outdone by indies, smaller companies, and as unpopular it is to say so right now, Nijisanji.
Hololive have basically mastered mediocrity and the art of farming simp wallets. They're the first stop for anyone getting into vtubers, they get first dibs. Their generalist pseudo-idol format is great if you're easily entertained by a cute voice and a pretty face, but they don't house much in terms of genuinely impressive talent. A couple of them can sing ok, and some are decent gamers, but that's about it. The spread and types of content they offer is very narrow, partly due to permission issues and partly due to the talent not really having any special interests or skills. Surface level fans tend to view them more as mascots than actual streamers.
Hololive will keep doing their thing and winning while the spotlight is still on them, and eventually they'll give way to someone who does something new and fresh, possibly revolutionizing the industry. It won't be any of the current companies. Definitely not Nijisanji, but almost certainly also not Hololive. It'll be someone else, a smaller act, a breakout star.
