Keep in mind with a remote reservior you loose the rubber seal inside the lid of the MC, that seal keeps fresh air out of your MC, which is a good thing for fluid life…

Yes and no on the remote reservoir exposing air. The really cheap ones with just a vent cap will expose air. But many have the accordion style seal just like the master you have built into the cap or the lid. You just have to look and see which ones do.
Like anything close inspection is the key on this one.
