The word "muddle" should use active or passive?

Question

When I couldn't distinguish two object clearly I would say:

1. "I got muddled A up with B." or
2. "I muddled A up with B."

I found similar expression in this question, and it seems both expression are correct. But I'm not sure which expression sounds more natural.

Answer 1

You could use either of these formations:

I got A muddled up with B.

I muddled up A and B.

I got A and B muddled up.

Note that the conjugation that you use with muddled up is not always with.
