I'm using 1.1.1.1 too. It's set up on router, though, without encryption. Router itself is really old, back from 2013, so it doesn't support DNS encryption. I'm instead using DoH via Chrome on PCs, and DoT on mobile devices via AdGuard.
Recently, 1.1.1.1 started to be a lot faster at my place. My ISP finally realized they could direct all Cloudflare traffic trough local internet exchange instead of Austria. Ping to 1.1.1.1 used to be around 10 ms, now it's 1 ms. Here's Google Public DNS for comparison.
