If they don't plan on implementing something like a "perfect-route", where you have to do certain things to unlock something, I hardly see a choice like this mattering in the end.
There might be some differences of one or two lines in dialogue, but I don't think that it would affect the ending or the playthrough much.
I chose Hades because he treated Asterion nicely, and I thought that he would appreciate it, if we offered his former lord the bundle.
When they still had the achievment rank (I think I got golden Peacock or something) in the game, I thought that that might affect the end, but it hasn't been implemented since, so now I think it wont matter.
