Both PC ports are shitty in their own way.
Demiurge added mappable hotkeys to Mass Effect 1, and easy access to the map screen, but ruined Garrus' face and messed up many outfit LOD textures, so it ends up looking worse in some ways, mostly in conversations.
Bioware added some mappable hotkeys to Mass Effect 2, but the screen promps don't reflect the remaps, the sprint and use keys are still bound to one action like on 360, the Galaxy Map uses the 360's boring navigation (clicking on a planet and holding isn't as kinetic as pressing directions on the stick). But, everything looks better than the Xbox 360 version and they sort of kept Demiurge's UI improvements.
