That may be the case from your own (presumably anecdotal) experience, however I took the Alexa top 1 million websites and queried for A* and CNAME against the www records for the top 10 000 domains. What I found is that approximately 44% returned CNAME records, 56% returning A records.
Code is https://gist.github.com/thpts/eb5cec361867170a0ffd6ede136c6649 here if anyone wishes to look. Regards * I realise that I could have added AAAA. My presumption is that the top 10k websites are not v6 only and at least have an A record in place.
