Oh. Like that.
Well it's basically a rule of the thumb that the older something is, the more durable it is. GameBoys are indestructible, I mean, there's even one that survived a napalm attack out there, but I wouldn't dare to throw my 3DS off a building for example. I even have first hand experience on the durability of the GameBoy. The Color in fact, but that makes it even better. My dog ate it once, or tried to anyway, but I probably told that story like ten times already here on VGC. Me and my history lessons...
The consoles are like that too. Though nothing ever broke on me because I take good care of my things, I know, by just feeling it, that the Wii and the WiiU are more fragile than my NES or N64. This isn't even Nintendo exclusive; sometimes I feel like my PS3 could break any moment if I even only look at it the wrong way (in fact, it did once, but I fixed it, the only system to ever break on me) while the PS1 on the contrary has seen much abuse over the years. Things as old as my Atari 2600, works as if it was new.
Concerning which is best, like I said generally the older the better, and the ranking basically goes from oldest at the top to newest at the bottom, but there are exceptions here and there.
The GameCube is one. It's a block of concrete. Once, my cousin yanked the controller too hard because he was frustrated about some game and the system flew off it's shelf, one-and-a-half meters high, through the air and hit the floor with the loudest noise possible. Like an anvil was dropped. There is no way any modern piece of equipment would survive that, yet GameCube did with flying colors. It had no scratch on it, not a single dent, yet the poor floorboards? They were split in two.
They just don't make 'em like they used to.
