I'm seeing there's some niche cases where it's worse (especially with some extreme quotation-mark-heavy searches) but I've switched a few months ago and never looked back.

The thing is: Most searches aren't even that complicated. Whatever "magic" (read: extra processing power) Google uses is mostly helping for extreme niche cases. The rest they seem to do, nowadays, is "editorializing" results, pushing popular websites before more relevant ones, displaying results from some internal database, etc.
