Is Linux stable enough to be used as a daily desktop OS now?

I ask, because I saw a video that was uploaded in 2011 and the the person who ran the channel, who was a techie himself, wouldn't recommend using the Linux OS as a desktop daily driver. It just had too many quirks.

So, I'm wondering in the 8 years after he uploaded his video, are his comments still relevant?

Thanks in advance,
