Hi, i am looking to learn an ARM assembly language as a newbie, i've been stumped by the choice between ARM32 and ARM64. Whilst i do have access to an aarch64 machine, i don't know which one is better to learn first. Do i take ARM32 because it is more standard, compatible and simple (i am assuming all of these) or do i take ARM64 because, well, 64-bits?

If it is up to preference, what are some good resources to compare them both?
