Evolution of the Varia Suit

Samus' armor has really changed over the years, hasn't it? From left to right: Super Metroid/Smash Bros. Melee, Zero Mission/Smash Bros. Brawl, Prime Echoes/Hunters/Corruption, Other M, Smash Bros. Wii U/3DS.

Personally, my favorite is still, and may always be, the Echoes/Hunters/Corruption design (the one directly in the middle), with the Smash Bros. Wii U design (on the right end) coming as a close second.

So, what's your favorite design out of these five?
