@r vs site:reddit.com
After a few tries, I also find the first more intuitive.
Unfortunately, having both search engines easily available led me to discover as much as I like Kagi I just use google more, despite its ads. Google is faster to get answers to simple questions (it usually answers them on the results page, without another click) and shows more results, although you need an extension for the latter.

Kagi has a quick answer feature: https://help.kagi.com/kagi/ai/quick-answer.html
If you add a question mark to the end of your query, it uses an LLM to generate an answer using the first few results (with citations to the sources).
The new snaps addition is something else: it gives you Kagi search results, but limited to that website. It’s the same as adding site:stackoverflow.com to your search query, but with an easier syntax (same syntax as bangs, but with an @ instead of an exclamation mark).
