what or that

[dewylotus]

What we can't get seems better than what/that we have.

Which one is correct? Can I use that there?

 

[Englishmypassion]

No, only "what" is correct.

 

[George French]

You will come across both forms.

Unbelievable and interesting.
But I am still in favor of "what" only.

Me too EmP. Maybe "that" could be used in some BE local dialect, but I can't say I've ever come across it. "That which we have" is possible, of course.
