If we want a microcoded architecture, I'd prefer the PDP-10, but that's me. How much more complex is a mostly-microcode VAX implementation compared to a MIPS?

If we want a microcoded architecture, I'd prefer the PDP-10, but that's me. How much more complex is a mostly-microcode VAX implementation compared to a MIPS? The point about being able to move stepwise up the hardware complexity ladder by progressively replacing microcode with gates is a really good one, though.
