I got the Madman version. The G1 episodes are the same as Shout Factory, so no Rhino sound effects. But there are a lot of animation errors in season one because it uses a mix of sharper looking but error ridden footage from the Rhino DVDs and the softer looking but less error ridden footage from the old UK DVDs. Not exactly the best remaster ever.

You do get the Shout Factory bonus features plus some Madman exclusive bonus features on the Madman version.
