Tachikoma or Acguy?

While I was browsing the net for new pictures to use for my wallpaper, I came across this picture of my two (current) favorite robots: Tachikoma and Acguy (from left to right), and thought, what the heck I wanna post this!

A Tachikoma is a fictional AI walker/roller tankette in the Ghost in the Shell universe, appearing in the series Ghost in the Shell: Stand Alone Complex and S.A.C 2nd GIG. Mainly used in Section 9's (a special police unit) chase missions, each Tachikoma (I think there were eight) was created with distinct personalities although they need to synchronize regularly as a protocol in compliance with the main objective of Section 9 to have Tachikomas act as if a singular unit. They are also curious, playful and opinionated.

I like Tachikoma(s) because their individuality was guided by their sense of justice and selflessness. One example was when they sacrified the satellite containing their AIs to prevent a nuclear explosion that might trigger further casualties during the government-refugee war. Of couse, Tachikoma provides the comic relief for the series.

On the other hand, Acguy (or MSM-04 Acguy) is an amphibious (toad-like?) mobile suit/Gundam suited for covert operations due to its ability sneak into bases undetected by enemy forces with the help of its twin reactors that emits only trace heat signature.

Although I'm not too familiar with its importance on the Gundam universe due to the fact that the only Gundam series I've ever watched is Gundam Wing (and I was mostly ogling the pilots not the Gundam), I liked it mainly because it was cute (rounded, burger-shaped and amphibious? hehe). Besides, it is the first Gundam model I received as a gift, so why not love your own?

So there goes my rant of admiration to the most adorable machines ever to walk on anime world.
