Thats not true anymore if youuse the OSS driver for the hammerfall.
Just be sure to start pd with the -32bit flag in order use the full
audio quality.

I have been working a lot with it and its about the best you can have
for running pd.

Unfortunately the ALSA hammerfall driver does not yet work well with PD
(AFAIK). The hammerfall is in some sense a very special card, and in
order to use its possibilities, the general ALSA code does not work.
You have to write specific "hammerfall" code. This has to be done yet
for pd.

You can not compare OSS/Free and ALSA in general (wrt to performace).
OSS/Free is an API, that does not have to do with the specific
implementation, whereas ALSA is a sounddriver framework where the
different drivers share a lot of code.
