Pratchett and Bujold are pretty much my top-two, which extends the the degree to which I feel compelled to share quotes. Both are rather character-oriented and often I find things (jokes, references, turns of phrase) on a re-read that I didn't catch the first time.

My main caution is that I wouldn't start with Pratchett's earliest works--there are already bunch of suggested reading-order guides out there. I spent a decade thinking Pratchett was overrated because I started with the wrong book. (IIRC The Colour of Magic seemed just too much of a parade of absurd situations for their own sake.) I like the City Watch books (starting in Guards! Guards!) and Small Gods is a decent stand-alone.

For Bujold, the Vorkosigan series is the flagship, where I'd put the Curse of Chalion (fantasy) as a second.

I can definitely recommend the Vorkosigan series by Bujold. That quote is from the first one, and echoes here and there throughout.
