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

Doing it any other way than what is officially specified in the manufacturer's documentation just leads to confusion. It makes much LESS sense to need to append special suffices to mnenomics when different register names would easily make the assembler able to decide.

Maybe it makes sense for those RISCs where the registers don't have any other names and the official documentation also does it like that, but x86 isn't like that, so stop trying to make it look that way.
