Speed wise and simple deployment, roadshow has everyone beat by a country mile really.
The author of Roadshow is accessible and easy to work with. Just install it, and it runs.
Easynet is a pain to setup by comparison, it does occasionally achieve similar speeds to roadshow, but it take more work and time to get going.
MiamiDX using MNI drivers has lots of features and attains decent speeds assuming your card has an MNI driver.
Genesis only used a few times. Nothing memorable for me.
Good luck.
