Mass Effect: Favorite & Least Favorite Alien Races?

My favorite species are Turians and Quarians. I think the Turians have the coolest and most interesting designs, while the Quarians have the most interesting culture and history. I'm not too keen on their supposed appearance given the infamous photograph, but they could easily retcon it for something higher-effort in the future.

Least favorite? I could cheat and go with the standard Volus/Vorcha/Batarians but of the prominent species, I'd have to say Asari. Half of their culture and design seems to be focused on making them sexy, rather than interesting.

I don't count humans because they aren't a species designed for the game.

Favorite: Rachni - An actual 'alien' species when compared to the veritable ocean of rubber foreheaded humans in the setting. The only species to actually heed Shepard's warning about the Reapers and prepare accordingly (being wiped out off camera notwithstanding); and even after all that, the Queen instantly sends support once freed from captivity no questions asked.

Least Favorite: A tie between the Humans and Krogan.

Humans because we are a race of Mary Sues in a galaxy that, for some inexplicable reason, worships the ground we walk on. We are a species so special, so "genetically diverse" that we are beating all others in their respective areas of expertise despite only being a part of galactic society for less than 30 years and everyone else having thousands of years worth of experience and infrastructure at their disposal. Better militarists than the Turians, better scientists than the Salarians, better economists than the Volus, better biotics than the Asari, etc.

Krogan because of the narrative bias in the writing (especially in ME 3) that saw them as blameless victims at the hands of evil, racist galaxy. No mention of their actions during the rebellions; redirected asteroids into Turian garden worlds anyone? The eating of captives for sport? No mention of how in the thousand years since the conclusion of that conflict that they have yet to do anything productive with their homeworld; all that greenery we see growing again in ME 3? Thank the Salarians for that one. All they do is sit around asking for a handout and expect the rest of the galaxy to feel sorry for them, and then, when people (who aren't Shepard) do start to work towards helping them, all they can do fling insults and bring up how poorly they were treated in the past.

Good call, silverhaku can delete it if they object.

Note: To give this thread 'Andromeda' relevance, humans are included because 'we are the aliens now' 
(and there's not going to be a heap of MEA news over the next couple of weeks...)

So, looks like the Turians got the first place.

What makes them your favorite? Is it the "Proud Warrior Race" trope?

Is it because of Garrus and his VA?

Something else?
