Concerning garphics, this machine had a different design than
the Amiga. It didn't have a shared memory (ChipRAM), but a
main RAM (1MB), a TextRAM (512KB), a VideoRAM (512KB), a
dedicated RAM for sprites (32KB -> 16x16 x128 = 32768),
and a SRAM (16KB). An interesting design to avoid botlenecks
I guess.
This is actually how most 2D arcade hardware does it with the exception that on an arcade board, most of it is ROM.

it's FM limitation to 8 channel (though it could sound cool on paper, it's a limitation using FM, because one voice is often created using several channel),
The YM2151 is a 4-op per channel synth and has a better selection of algorithms than OPL3. There isn't a lot of need to use multiple channels for one note.
Personally, I think the X68000 is a better game machine (hardware wise anyway) than the Amiga, but the Amiga is a better home computer. Generally speaking, the tilemap and traditional sprite approach of the X68000 is more efficient for games, but it sucks for drawing windows, variable width text and any number of other home computer tasks.
