Is MASM good?

I am just beginning ASM. I have A86 and I read a tutorial which said to get MASM32, I got it, Is it any different than A86? does it have any disadvantages? I had no problem with A86 but I only use Windows and I heard I should use MASM but didnt't hear why.

a86 doesn't give you 32-bit code unless you get a full version. MASM is explicitly made for windows.

Personally, I have NASM. Its a nice assembler and its free.

How its set up though is that you really cannot assume anything. It helps readability but it is a pain sometimes.
