You do realize these are very different games right?
Immensely different really. xD
It depends what you want obviously.
Deus ex being an action heavy story driven game. (I think the story is supposed to be good? o-o)
Catherine having a puzzling gameplay, but has a terrific story and is interesting in dealing with the issue of relationships.
I have no idea what Child of Eden is like except I'm sure it has lots of bright and fantastic colors. (I'm not saying you shouldn't get it, I just don't want to do research to find out more about it)
I'd definitely be torn between Deus ex and Catherine, but I already got Catherine and it was a thrill ride in terms of story. Deus ex looks to be more killing and action driven than Catherine's puzzles. So basically it comes down to the game play that you like.
Seriously though this comparison is like comparing Scott Pilgrim vs. The World and Inception. Both really good films, but have drastically different styles.
