For the millenium TCi (based from personal experience kasi we owned a SVX M/T and currently have the Club A/T)

M/T:
Pros:
- Quicker response
- Hindi boring sa long drives
- Easier to maintain
- Pwede pa itulak para mag-start kapag low power ang battery

Cons:
- Nakaka pagod sa long drives

A/T:
Pros:
- Relax driving
- Very convenient in long drives

Cons:
- Sluggish
- Sluggish
- And sluggish

Mabagal talaga ang hatak, seriously.
