After replaying the entire trilogy a few times I am more convinced than ever that Mass Effect 1 is the best game of the series.

Is it the most polished game of the series? No, that's ME2.
Does it have the smoothest combat of the series? No, that's ME3.
Does it have the best-written character/character arc of the series? No, that's Mordin Solus.

But what it does have is the most cohesive design and story, an interesting universe, a great soundtrack and by far the least amount of fan pandering.

It also runs quite well on PC. It does not have a wide array of in-game options or settings but if you are willing to edit some of the .ini files you will be able to really make the game shine.
