Please, don't start again. The F030 was STE/MegaSTE sucessor. The true flag ship (a TT successor) was the never released Falcon040 because mearketin people in Atari were idiots
And also want to compare only the 3D speed.
Because OP wanted it so.
Answer: The Amiga 4000 has great expandability (32 bit slots -Zorro III, ISA, video slot. The Amiga 4000T has both built in Fast SCSI 2 controller and HD floppy (HD=the ones from Commodore. 1.8 MB), (I had one), the 4000 also had HD floppy.
That is not a much for that price, don't you think? The one truly highend component was the SCSI 53C710, but in 1994 and later most user would have rather a second IDE channel and ideally UDMA support. BTW, to make the HD floppy working the revolution speed had to be halved to allow functionality with the onboard DD controller. The floppy was thus half speed compared to normal floppy.
