Apple claims their Apple Silicon is much more efficient than Intel's CPUs. Is that because ARM is an inheritly better architecture or because Apple is better at chip design than Intel?

ARM is a totally different architecture, and it is a better architecture, than x86/64.  

X86/64 is supporting 50 years of cruft and backwards compatibility.  ARM isn't.  ARM is a simple ISA, x86 isn't.  ARM is a RISC ISA, x86/64 is a CISC ISA, which Intel translates on die to a RISC ISA that they run on their hardware.  ARM doesn't have to do that.  

There's a lot of deeper things to go into with it, but that's it in a nutshell.
