I never saw Armada, but I did pick up the Generations Armada Starscream when it came out and enjoyed the figure quite a bit.

The one thing that surprised me with Legacy Starscream is how solid he feels, there are only two obvious places with hollow area's and that is his thighs (standard for most transformers these days, and the back of his shoulders. I would argue that the shoulders one couldn't be avoided as that is necessary for transformation to allow his arms to slide over. This is also where my biggest complaint with the figure comes in, the shoulders annoy me as the arm comes loose when pushed back, and the arm is very easily pushed back. However credit where its due, when the arm is in its robot mode configuration the shoulder design does lock it from being moved side to side, its just the backwards movement that causes issue.

The second issue I have is that the sword doesn't form from his wing. The rest of the figure really looks like the cartoon version of Armada Starscream and it would have been nice to have that one feature, but at least he still comes with the sword in some form.

All that being said, those are fairly nitpicky issues I have with the figure. Legacy Starscream has a good solid feeling figure and just the right amount of heft to him, it's something that a lot of figures in recent years have been lacking in my opinion.
