You should just get the console which ever you think is better Ts. Why want to bother to ensure that both is better?

Imagine if there is only 1 console in the market who dominates all, will there room for improvement?

I got both and enjoy both just for the exclusive title. Developer have the right to choose which console they should work on.

It's not easy as you think to be working for a multi platform title. If the game turn out to be bad, they can't reverse time to correct their mistake. All they can do is learn from their mistake and makea better 1 in the future.
