Yep, I'm another Google user. It has a hugely large index, so chances are whatever the other search engines have, Google has it too.
Also, something I really like a lot is the fact that the home page loads so very quickly because it hasn't been filled with adverts - especially flash and DHTML animations. Nice and simple layout, just a logo, a search field and a few hyperlinks... can't say that about many other sites (although Booble is like this too, iirc).
Lastly, I also like the stuff they produce at Google Labs. If using Google as my preferred search engine helps fund (indirectly) the development of GMail, Google Earth, Picasa, Froogle, etc... then I'm all for it
