How would you say dwm compares to i3?

To my knowledge, there isn’t. That’s why for the time being, the best search engine I have found is DuckDuckGo. If you really wanted to go all out, use SearXNG, which is FOSS, and relies on self-hosted platforms, however it requires a bit of tweaking, and some instances seem to be blocked on some harsh work firewalls, at least in my experience.

The alternative is ublock, or a well-tuned noscript.

You might be a tad disappointed…
