None 😜. I'd imagine the SB Live! would be kinda better, but only when it comes to OPL3. OPL2 sounds absolutely horrible on the Live!. Compatibility is also very hit or miss.
The Vortex 2 is quite a bit better in terms of compatibility, but it's FM Synth emulation is also pretty bad.

I always say you can't really go wrong with a good Yamaha PCI sound card and SB-link/PC-PCI cable (if your motherboard has an SB-link connector of course). It still does a good job without the cable via emulation though 😀.

Are there actually any Creative PCI cards that can use the SB-link cable?

I see, thanks!
I wanted to sell my audigy, but im too attached to it 😁
Bought it a few years ago on a flea market for less than a dollar. Perfect condition.

There was atleast some AWE 64 pci card from creative that could use SB-link connector

AWE64 PCI

Well, I've had both cards and I never really managed to get Live! working under DOS. But I did manage to do it with Audigy, so my vote goes there 😜

As for the quality... Meeeeh.

For me is the opposite, i managed to run Live under DOS 😀
But never tried Audigy.

I dont really have much use for it, some person asked me to sell it, thats why i am asking.

You can use Audigy 2 in DOS with the Audigy's DOS drivers.

Both Live!'s and Audigy's emulation of SB cards in DOS is somewhat similar.

Both are troublesome to make them work, but can be done for those who have no other options or do not have access to othe PCI soundcards to make them work in DOS.
Both have expanded memory requirement to load, and games that are not fond of EMS will cause problems.

Ironically, third-party makers that run on other chips like Aureal's Vortex I and II chips, ESS or Crystal chips have much better support for SB emulation in DOS compared to Creative's own Live! and Audigy series. Thanks to Creative's legendary drivers reputation, including it's own DOS emulation of it's OWN cards.

They both require the same legacy ISA support in the motherboard, right? (I never did get to the bottom of that.)
