They are exactly the same. Same running number, so probably just going into a bigger box at the end of the assembly line along with some tracks.
I don't get why people cannot just enjoy the fact that they can get a good value package. I get why it is annoying to have paid for another set, but isn't that just the way life is? Deal with it, and do not complain. Complaining gets you absolutely nowhere.
Sam has a grudge against Hornby (for some reason I, at least, do not know). He also lacks insight into how models are made, since he keeps suggesting that smaller should be cheaper. That is not how manufacturing works. It is not the materials that cost, it is the development, and that cost is in the same ballpark no matter the scale.
I used to enjoy Sam's videos. Now, I don't enjoy them that much anymore. His behavior in some videos also hints that he is seeing himself as a voice that matters, like the Bachmann video where he threatens them "I dare you" he said. Nothing good usually comes from being too sure of your own relevance. I don't like that.
Personally, I like a review when it is not filled with personal opinions and grudges. Just let me see the model and listen to how it performs. I also do not care much about what the box is like, because we have all seen that a thousand times or more. 😊
