EPGP or DKP are the best.
I have used both and both reward the people who show up consistently. With both you can always award a bonus for fast clears, new bosses downed, near perfect runs, etc which is very nice.
Loot Council is BS because clicks are formed, people become fake just so they can get loot and its just bad unless you are using it for a 10 man guild in which case it might work fine.
