What's Best Twitter software? or What Do You Use?

I'm looking at getting some Twitter software this week.
I'm open to suggestions/advice on what others use and find successful.

Ideally i need to create Twitter acc's, Tweet, Re-tweet, Follow.....all the things the main software will do.

I'm aware of Tweet Attacks Pro and only just been made aware of TWT Dominator. Anyone any experience with these or any others that would be good.

Thanks.

The truth is, the custom made ones are the best!
