I never had the Frenzy and Rumble ones, so this is all new for me, nor can I compare them. But wow. Rosanna here is basically a minicon. Except about a billion times more cool and posable. All her joints are super tight an hold really well. The swords peg onto the hips and stay put. The pegs for those are pretty tiny. They don't feel flimsy at all, but I wouldn't put too much pressure because they are small and will break if you're not careful. The waist rotation is nice and part of the transformation. Because all her joints are ball joints, it means she has built-in knee and elbow swivels. The large cannons can mount on her arms, or on her back. The gun mode's grip becomes a pistol she can hold as well. The gun mode has a standard 5mm grip, so figures such as Classics Prime and RtS Jazz can hold her with ease. So it's a great Targetmaster upgrade to a lot of your existing figures. Overall, this is an awesome., if not pricey, little piece. I highly recommend it. If you don't like this color scheme, wait fro the Eject and Rewind versions.
