Nintendo's best is Game Boy Advance. Their worst is 2DS. Although the name makes sense, they couldn't have caused more confusion if they tried. It's not talked about as much, but the 2DS still causes more confusion than the WiiU.
Sony, well, PlayStation Portable wins for me, sure it ain't creative, but it can't be any more blatantly obvious either. And it abbreviates to PSP, which I always liked. Vita is an interesting name, but I can't help feeling it's also kind of bland and nonsensical.
Microsoft... I can't say I'm crazy about any of the names really. I guess just calling the Xbox 360 a "360" is the high point. The abbreviations for their latest console like X1 and Xbone aren't too bad.
Sega... Sega was just always cool with the naming. Can't fault it.
