a lot of collectors including myself have never played the Arkham Games so it comes down to which Joker appeals to you more in Statue Form.You collect the one you like,simple as that.Or ones you like if you can afford it.
If you have played the Games then you most likely already have a preference.You can only hope the transition into Statue form,Face Sculpts,Clothing,Pose and Base are what you are looking for when that version is released.If not then you continue to wait.
This is the same scenario for all the Arkham characters being produced into Statues.Knight,Origins,City,Asylum,will your fav be turned into what you want?Sculpt,clothing,Pose and Base?
looking at all the Jokers from game play on YT.. City,Asylum and Knight look very similar.Origins seems to be the exception,a completely different look.
