First, it's sad to see that the two answers you got are not answers to your question.
Unfortunately, it's common on this forum.
Unfortunately, I have no experience with the kits you're asking about, but if you search on Google for example, amati occre titanic, you'll find information.
You can also search on youtube to see the contents of the kits and also what they might look like when built.
If I were to buy one of them, it would be Occre, mostly because it's significantly cheaper and seems detailed enough for my taste. It's also a little smaller than Amatis, fits in a bookshelf that's about 100 cm.
One more thing, if you buy the Amati kit, make sure you get the updated one.
There is a big difference between it and the one Amati had before.
