Rod Land, which version(s) to play?

[Lord Mushroom]

I wanna play Rod Land, and after watching You Tube videos, the Amiga version seems better due to the vastly superior in-game music. However, the Arcade version has many brand new levels after you complete it, which I don´t think the Amiga version has. And furthermore, these levels can be played without completing it if you use a simple code.

 

So I thought I would first complete the Amiga version, then play the extra levels on the Arcade version. Does this sound optimal?
