Do you prefer an Xbox One S or the One X?

I'm considering whether I should buy an Xbox One S or the One X, because my budget is low, the One S would be more of an option.

But what about the One X? Is it worth saving and waiting for it or is the One S enough?

Why not the Series S.

Also costs less than 300 euro and is the better console since it is newer. But without a drive!
