1.1.1.1 should be fine.
Big picture: consumer internet service providers (ISPs) typically run their own DNS. These DNS servers may be slow, and/or may be redirecting invalid addresses to some sort of annoying, unwanted website, such as one that offers to sell you the domain name, and/or they may be aggregating and selling usage information to advertisers. They may also have weak security.
Instead, the better alternative is to use one of several free, high-performance, high-security DNS provided by third parties. These DNS do not perform unwanted redirects, are geographically diverse, have very high performance returning queries, and typically have better security.
A few examples are:
1.1.1.1: Cloudflare -- supposedly the fastest DNS
8.8.8.8 / 8.8.4.4 Google public DNS
9.9.9.9 "Quad 9" DNS, operated by IBM and a consortium of security companies
Use whichever one of these you want.
