Yes, x86 is weird but the variable-length instructions are actually nice and easy to understand, once they're unpacked to text form anyway. The problem with them is they're insecure, because you can hide instructions in the middle of other instructions.
I think the biggest thing you learn in x86 assembly vs C is that signed/unsignedness becomes a property of the operation instead of the type.
It would be cool if you could use flags, which is easy/easier on some architectures like PPC/armv7, but x86 overwrites them too easily so it's too hard to use their values.
