Is it just me, or was the AHA-1542CF the BEST disk controller ever made for the AT Bus? SCSI, MFM, RLL, IDE -- doesn't matter which -- Was there ever anything better than it?

For those of you not familiar with it:

Adaptec EZ-BIOS that pimp-slaps even the crappiest AT BIOS into shape, floppy controller (that always seemed 'faster' somehow), software level turning on/off termination on the card, Configurable to a half dozen different ports, ability to co-exist with other cards of the same type, that nice big robust 50 pin Centronics D on the back instead of the rinky little crap that came later... The ENTIRE 154x series were absolutely great cards, but the 1542CF was like the pinnacle of the art of making a disk controller.

I mean, I'm sitting here with a 10mhz 286 that's got a 4 gig 10K RPM Seagate Cheetah... So I'm pushing 2.8megs/sec according to Norton's Sysinfo, even with the warning about the disk controller blocking the seek time test.
