I'd argue youtube's search is far worse, given it intentionally includes entire sections of results (and toward the very top of results) that are categorically off-topic, presumably with the intention of distracting the user into spending more time on the platform, and they can't be turned off (I tried some uBlock filters but they're hit and miss). I think distracting ads in Google results are a necessary evil (i.e. ads are distracting, but it's hard/impossible to show ads without them being distracting, unlike those undesirable sections in youtube search results).
