Definitely. It is just a handy multiplexer - I have a habit at this point to append every query with a bang.
On the occasions I forget, the DDG results seem to be improving. However, ~90% of my Google queries are computer related, and DDG (and even the !so bang) are not as relevant as Google yet for me. As soon as this use case improves enough, I will break my bang habit and use DDG directly for most of my queries.
