[Godzillaprime05]

Kiryu, SMG, and Mechagodzilla

[Living Corpse]

Mecha-King Ghidorah.

If only his execution was better.

[JAGzilla]

Showa Mechagodzilla. He succeeds on pretty much every level.

Alien death machine? Check.

Visually cool? Check.

Effective and varied array of weapons? Check.

Gave Godzilla several good fights? Check.

[Goji]

Showa Mechagodzilla. No contest whatsoever.

Second would be Mechani-Kong followed by Jet Jaguar.
