I've been researching both lately.. The Pebble is an E-ink display so its monochrome but lasts longer ("7+ days") while the Smartwatch is an OLED display which lasts around 5 days according to Sony. Also, the Pebble uses buttons for navigation while the Smartwatch is "multitouch" (9 points in a 128x128 display). The biggest difference IMO is that the Pebble supports both iPhone and Android while the Smartwatch only supports Android. Also the Smartwatch is a bit bulkier and it sticks out more as its really thick.
