Although "Thriller" is no longer under development, it has one very major thing going for it - the "HSDPA Category" is changed from 8 to 10. Apparently either AT&T or LG or both have decided that setting the "4G" to the fastest setting was too much for users to handle.
One I updated to Thriller ROM, my speeds over HSDPA more than tripled. Before, i was hard pressed to reach 2 Mbps download, now I average 6-7 Mbps.
I don't know if any of the other ROMs have also made this change.
