How do Micro galaxy squadron scale with WotC minis?

I started collecting WotC minis for my SW d20 RPG campaign and I'm looking for the best ships and set pieces that are also moderately inexpensive. Has anyone compared them to the Micro galaxy squadron line? Those come with like 1in minifigs, right? So I'm guessing their close to scale? Not a perfect 1:1 probably and it might vary per ship, but are most at least kinda close?

If not do you guys have any suggestions? I'm looking for all kinds of ships from empire, to rebels/new republic, and stuff I could repurpose or kitbash with.
