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

The first x86, the 8086, is 3 (or 4 if you count the 8085 as being separate from the 8080) families ahead of the 4004 and 8008 and quite different from them.

AMD is too secretive. Try finding the socket AM3 pinout for example. Intel lets you know what every single one of the 2011 pads on the latest CPUs are for. The quality of Intel's manuals (# of typos) went noticeably downhill when they switched to the "new" style of font/logo and probably new people, a few years ago. I still use the ones from P4 days.

I'm guessing that having 1:1 correspondence between mnemonics and opcodes would make the assembler's job simpler, but I've not written one myself.
It would, but at the expense of being able to write Asm easily.
