Best X86 Assembler - FASM vs NASM vs MASM?

So I'm looking to learn x86 assembly and I wanted to know which assembler is the best.

I hear FASM is the fastest assembler, NASM is buggy, and MASM is Macro$hit so it is probably slow and integrated with .net

ax and eax aren't different registers. why call them by different names when it's actually the operation being performed on the register that's different? it makes much more sense to indicate the size on the opcode name than on the register name.
