I've only experienced the HP cards which used proprietary 10/100VG Ethernet, so it's hard to compare it with modern 10/100 equipment. But, even on the 386 and 486 machines at the time they were very fast. I never got a raw transfer speed but you could definately tell the difference between the 10Mb cards. Just a note that even at 4MB/s that's more than 3 times the speed of a 10Mb card which is "why".
