I'm using the ymfpci driver that comes with 2.4.9. (Distribution
doesn't matter here).
The only way for you to find out whether there is a significant
latency difference between the drivers on your specific system is
to benchmark. Grab Benno Senoner's latencytest program at
http://www.gardena.net/benno/linux/latencytest-0.42-png.tar.gz and
benchmark yourself. There may be something specific to my laptop;
who knows?
I haven't traced the source of the latency yet, but my first bet
is the snd-pcm-oss module, and the second bet is snd-card-ymfpci.
