I was in the same boat as you, I had no experience with a Midas console, but obv I heard so much about them. All the good blurb I heard was enough to solidify my decision to stick with them. I ended up buying a Venice F32 and havent looked back since. Currently looking to purchase a even smaller console, but I've heard next to no information on the U16 or U24, no price, no manual, no dealers.
As to your other question, yes MON1 and MON2 can be switched both pre/post EQ AND pre/post fader
