So I've recently discovered some of DCs out of continuity titles like Justice, The New Frontier, and Kingdom Come, and I want to buy one. I wish I could buy more than one, but I only have the money for one of them. Knowing that there are more great Justice League TPBs than the three I've already found, I've waited on buying any one of them to ask the interwebz for their advice and recommendations.
So for someone who is really pretty new to reading DC, which Justice League trade is the most iconic and best represents the team as it is?
(I've been reading the New 52 Justice League titles, but I know that it isn't even close to what the ensemble could be, if Justice League DOOM is any indication.)
