I am sure there is a good reason for this. I am looking for alternatives to google, and these to be the ones that pop-up most often.
RESOLVED: I used up my 100 searches in kagi pretty quickly, and the experience was really nice. I am quite anti-subscription, so I won’t continue using it. I eliminated brave from my search due to the crypto stuff and whatnot. I am now using mojeek, which gave me better results over DDG when searching for niche stuff. Also I like mojeeks interface a lot more.
Nowadays it’s always needed to use several search engines to fullfit a deeper research. If own or third party search index is irrelevant, every search engine handle it in a different manner. More important as this that the search engine don’t logs your activity, this is given in most search engines, except Google, Bing, (Brave) and Yahoo. Startpage, Mojeek, Ecosia, Qwant, MetaGer, Swisscows (if you have childrens and need a Family safe search) among others, are very valid. Also usefull searches of specific pages (WolphramAlpha, Wiki, Forums, etc) and to add also analytic pages as search engine (Blacklight, VirusTotal, Webbkoll, etc), to check unknown URLs.
