SCSI. Buddha is IDE. Again, I'd take a simple 2091 card over buddha its cheaper. A gvp scsi with memory is better than 2091/Buddha. All those SCSI cards are on ebay from time to time. Also, SCSI on Amiga was always better as IDE was not so much mainstream back then on Amiga. A4000 had IDE, A4000T had both (and SCSI was better on it).
