It's not the alternative. With DoH you are sending DNS queries, IP addresses, OS information and possibly even tracking cookies to Cloudflare over an encrypted channel, but Cloudflare still makes plain text queries to authoritative DNS servers from there. While your ISP's network is actually private, sometimes even encrypted, and sending plain text queries over it to its DNS servers is almost the same as having an encrypted channel. On top of that whether you use DoH to Cloudflare or not, your ISP sitll has the ability to spy on what websites you are visiting and in fact is what an ISP typically would use for that purpose anyway, not DNS data.
