Yeah, it's worth it if your going to do something on the Amiga that requires exact timing or optimization. If you were going to show 30 sprites within 40 microseconds to simulate particle motion or something like that, you wouldn't want to use C. It would be too difficult figuring out how many cycles a function call takes for example to set the palette within the HBLanking period unless you wrote something like:
Move #16-1,D1
Move.l #$DFF180,A0 ;hardware color register #0
Clr.w D0
SetPalette: Move D0,(a0)+
Add.w #$111,D0 ;next shade
Dbra D1,SetPalette
This following item also comes with simple 68K Assembler/linker and lets you bypass the Amiga OS so you have access to all the hardware resources:
