Best Bot and Class

I am going to start botting and I was wondering what the Best bot and what the best class is for botting? So basically my 3 questions are:

1. Best Pay Bot-

2. Best Free Bot-

3. Best Class to Bot for Money

Thanks!

I'd say the best bot would be one you make yourself, the other bots aren't maintained very well generally.

Best class to bot with is most likely the venomancer
