Having been a k2 user since day one, back in the dark days of joomla 1.5, I have rebuilt and rebuilt right through to joomla 2.5. Using Artisteer 4 to build my templates and Adobe fireworks for graphics etc, I am fairly happy with the results: www.ojchillies.co.uk K2 gives me everything I need to write my blogs and set my site out exactly how I want it. I have tried many other blog layout components but always end up coming back to K2.
