FWIW it's probably because a lot of us have been following along and trying these things from the start so the nuances seem more obvious but also I feel that some folks feel your question is a bit "stupid", like "why are you suddenly interested in the frontier of these models? where were you for the last 2 years?" And to some extent it is like the PC race. Imagine going to work and writing software for whatever devices your company writes software for in whatever toolchain your company uses. Then 2-3 years after the PC race began heating up, asking "Hey I only really write code for whatever devices my employer gives me access to. Now I want to buy one of these new PCs but I don't really understand why I'd choose an Intel over a Motorolla chipset or why I'd prioritize more ROM or more RAM, and I keep hearing about this thing called RISC that's way better than CISC and some of these chips claim to have different addressing modes that are better?"
