Which hero is the best at level 1-1-1?

You can't level up/upgrade him.
You can choose mages.

The purpose of the poll is to determine who to choose at the start, someone who may or may not become a leader later, but will help you get ahead.

Get ahead against whom? If it's against monsters, the criteria will be different. And very few people manage to get ahead against enemy heroes in the first week...
According to the statistics of online tournaments (vbn, I posted it somewhere), the leaders are Valeska, Kirr, and Galtran.
