Its nothing to major , but the look and feel to it, the quick access to everything.
Ive tried mxm i like it alot but takes 10 years to load, avalaunch is nice , the features are cool but it hangs alot.
The only thing i was using exo-x for was to ftp because my main dash was the m$ hack with no ftp.
Unleash runs on my box now , even with the open and close dvd saves me having to get up lol, I have cut out rebooting the xbox by at least half with unleash, file manager is brilliant everything about it, the quickness of the menu's , is not perfect but in my eyes its not far off, oh and plus the skinning is good
