The results aren't all that sub-par. For technical questions specifically, they're actually (anecdotally) much better. And the favicons besides the results are a godsend. The only thing I use Google for these days is when looking for something like a company in my area. Because of all its knowledge, Google knows I probably want the "Radio City" in my country, not the one from Toronto or whatever. But those cases are rare predictable, so I prefix it with !gsi without even thinking about it.
