much much better
boot up to Kodi in less than 10 seconds.and the animation,perfomance is silky smooth thanks to the Quad Core

apparently you can
just normal install Raspbian. then you can install Xbmc on top of it
official guide = https://www.raspbian.org/RaspbianXBMC

the fastest method is using the binary install
http://michael.gorven.za.net/raspberrypi/xbmc

OR, the easist way is, just install a browser addon in the XBMC/Kodi. bet it would work like a charm

p/s : just realised that in the page mentioned that it would take 12 HOURS to compile them from source. hopefully not that long on RPI2

If you are using the rpi only for media, try osmc.tv, the evolution of raspbmc. Very good UI, and stable. Auto updates, so not much of tweaking need to be done.
