It's not only hostap. I think something gone wrong with ath driver.
This is with

Setup is exactly the same: same ap, same environment, same distance from
the ap... I've only swapped cards.
Maybe is it related to this bug reported in the ath(4) manpage?
Performance in lossy environments is suboptimal. The algorithm used to
select the rate for transmitted packets is very simplistic. There is
no software retransmit; only hardware retransmit is used.
