ARM32 is much simpler to explain compared to ARM64. Registers are so much simpler, conditional execution is orthogonal, three-operand form is consistent. ARM64 made all the right practical choices, but has doubled the complexity. Still much better than x86 with its 10x complexity. ARM32 is a gem, in my opinion. A truly simple instruction set, and easy to get your hands on with Raspberry Pi or emulation.
