| Pros of mechanical gear | VS | Pros of magnetic gear |
| 1. High very high torque/mass (specific torque) | 1. Non-contact | |
| 2. High very high efficiency | 1.1No lubrication | |
| 3. Mature technology | 1.2Low maintenance | |
| 2. Easily integrated in electric machines | ||
| 3. Potentially low vibration | ||
| Cons of mechanical gear | VS | Cons of magnetic gear |
| 1. Contact-related wear failure | 1. Unknown limits on specific torque efficiency | |
| 1.1.Requires lubrication system(s) | 2. Magnet temperature limit | |
| 1.2Routine costly maintenance | 3. Individual magnet interaction weaker than 1 gear tooth pair | |
| 2. Strong tonal vibration cabin noise |
