Well, when thinking logically, the A2000 should go. The A3000 is technically a better computer, while the A2000 would need quite some expansion to reach the performance of a standard A3000.
Otoh, I own both and if I really had to choose, I would let the A3000 go, I guess. I use the A2000 more, even if both my A2000 and A3000 are more or less comparable to each other (both have an 68040, RTG, X-surf, SCSI-harddisk and extra fast ram).
Tbh, I'ld keep both.
