Yes and no. You used to find niche websites more easily, but I vividly remember the frustration with ExpertsExchange results (with answers that were all paywalled).
This is one of the reasons why Kagi is so good - you can easily set it up to downrank cesspits like ExpertsExchange or Quora into oblivion.
I was around as well and my memories do not confirm this. But google search definitely degraded a lot.
