As background, i had raspbmc installed with my pi 1 B+ and i wasn't happy about it because of lack of wifi dongle drivers and lack of smoothness / response when browsing..
Nowadays, after spending some more money, i have successfully set up a media centre with my (brand new) pi2 with OSMC, and i'm happy with it (e.g.: last night i could reproduce 1080p from a SAMBA fileserver without any issue )
But OSMC is not the only operating system out there regarding media centers so the main focus of this post is the following:
what are the main differences between OSMC, RaspBMC, OpenELEC, XBMC and KODI?
Which one is recommended for RPI / RPI2 ? and why?
I know that there have been some comparisons previously, but with the launch of pi2 and OSMC some of them are outdated. (example: http://www.htpcbeginner.com/xbian-vs-ra ... lec-part1/ )
