ecosia seemed to work slightly better than ddg for me recently, but there's some controversies regarding their greenwashing and union busting

qwant seems to be pretty good but they geoblock specific countries including mine. it works through a vpn tho

startpage is just google

etools.ch is quite nice, even works without javascript but somehow they're not so popular..

yandex is decent quality wise, but i get endless captchas from them for some reason
