1.1.1.1

I have not used it.

I use Quad9 DNS.
9.9.9.9 is with malicious sites blacklisted.
9.9.9.10 is open.

Why use 1.1.1.1 instead of an ISP’s resolver?

The main reasons to switch to a third-party DNS resolver are security and performance. ISPs do not always use strong encryption on their DNS or support DNSSEC, which makes their DNS queries vulnerable to data breaches and exposes users to threats like man-in-the-middle attacks. In addition, ISPs often use DNS records to track their users’ activity and behavior. These resolvers don’t always have great speeds and when they get overloaded by heavy usage they become even more sluggish. If there is enough traffic on the network, an ISP’s recursor could stop answering requests altogether. In some cases attackers deliberately overload an ISP’s recursors, resulting in a denial-of-service.

For a normal user, who browses and downloads, how exactly is this or any other dns helpful? What does fast mean, I mean does it increase the download speed etc.?

It won't speed up your downloads but will let the download start earlier.

For each website address we enter in the browser such as www.digit.in there is an IP (internet protocol) address in the format of xxx.yyy.zzz.aaa (eg. 236.76.167.5) which is the actual address computer understands. So your browser has to lookup the corresponding machine address for each webaddress for the site to load. This service is provided by DNS servers. Generally your ISP provides this service. There are also independent providers like Open DNS, Google, Quad9, Cloudflare etc. Because they have better servers nearer to you, their service is sometimes faster.

For many things involving a webaddress this translation/lookup has to happen. Hence a service that provides quicker DNS lookup improves your browsing.

Google, Cloudflare and Quad9 have servers in many places.

If you want to go technical and very deep into it, you can use dedicated software to analyse dns performance. On Windows I use DNS Benchmark by Gibson Research Corporation (GRC's | DNS Nameserver Performance Benchmark  )
You can also use 'namebench' which is open-source and cross-platform.

A dns is like how fast you open the door. Someone rings the bell ( you type an URL ) and the house owner takes some time to come to the door and open it, so that the person can come in

It all depends on how fast he opens the door. An URL need to converted to an IP before it served to the browser. DNS resolvers makes these conversions faster.
