I'm a fan of RISC-V but the freedom is a large part of it. Aarch64 is a very well designed ISA and clearly has a lot of benefit of hindsight. The load pair/store pair instructions, the addressing modes, fixed 32-bit instruction size, etc. It all really helps. I suspect that Apple was actively part of designing it.
I think however that RISC-V isn't that much worse and because of the freedom we will almost certainly see more implementation of RISC-V. I'd be watching Tenstorrent, SiFive, Rivos, Esperanto, and maybe Alibaba/T-Head.
