Extracted iso's give you the most flexibility and takes the least amount of time to put on your 360.
With God's you have to extract the data from the ISO's and then convert it into a GOD then transfer it by whatever means to the 360. And the directories are not exactly readable by human.
Using extraction method into self named directories under a games directory (internal or external) you can actually read what you have there, and you can then modify data if you ever need to for the game. Can't do that with a GOD that I am aware of.
And obviously if you had GOD containers on an external drive, it would have to be HFS+.
