I can definately say that PANG was a very good port indeed. It is pretty close to the arcade original.
I think another good port was Snow Brothers (Snow Bros) (unfortunately it was never officially released on the Amiga).
You can get it off the AGTW (Amiga Games That Weren't). I think Ocean France possibly made some of the best Arcade Ports on the Amiga.
The Liquid Kids port also looks quite good. All of the sprites were traced off the Arcade version by-hand. I think the same was done for the other like Pang, Toki, etc. Shame Liquid Kids also was not officially released.
