USA vs JAPAN: Boss Themes

The mood of the boss' music would show how challenging Robotnik/Eggman could be.

Japanese Versions 

Main Theme

With laughing and voices that are a small part of the snappy tune.

Tune: 4/5
Boss Relevance: 2/5
General Likability: 3/5
Total: 9/15

Final Theme

Now aided by vocals, this beautiful yet insane mix puts the battle in focus.

Tune: 5/5
Level Relevance: 5/5
General Likability: 5/5
Total: 15/15

American Versions 

Main Theme

A bleak song with metallic sounds and creepy laughing.

Tune: 3/5
Boss Relevance: 5/5
General Likability: 3/5
Total: 11/15

Final Theme 

Very similar to the main theme, this desolate take is arguably more creepy. 

Tune: 3/5
Level Relevance: 4/5
General Likability: 3/5
Total: 10/15

Conclusions? 

While the North American version is creepy and better suited for a boss battle, the Japanese's final is better and more focused. That makes it a tie, so for the winner as a whole I'm seeing who scored the most points.
