Telstra, Optus and Vodafone: which is the people's favorite?

Telstra, Optus and Vodafone which is the most favorite of people ? Is there any data or picture can show me?

Hi Eason

We use Telstra - it works. 

All as bad as each other.  I can't believe my Optus phone works better in Hong Kong or Bangkok than what it does in Perth.

I use Telstra most, though I've used all three. I find the higher cost payoff for Telstra's better network is worth it.

Telstra for work and personal, Ive been on Voda, 3 and Optus (virgin) and telstra is far far superior/.

For frequent flyer points addicts, they would go either for Optus for Qantas Frequent Flyer points and Virgin Mobile for Velocity points. Virgin Mobile piggy backs on Optus network so essentially, their coverage is the same.
