The Xbox OG had zero expectations going into its generation and got off to a pretty quiet start sales-wise, but over time it managed to claw its way into being the main competitor to the monster that was the PS2, and pretty decisively beat the GameCube, a system from a long-established manufacturer that by all rights should have held every advantage over a glorified SFF PC from a newcomer.

The Xbox Series was, at the start of its generation, the console pretty much everyone wanted to win thanks to Sony's mis-steps at the turn of the decade. And it actually kept pace with the PS5 pretty well for the first 18 months or so of the generation. After that, however, everything slowly fell apart, leaving them ironically in pretty much the same position as the GameCube was at the comparable point in its generation, i.e. no-one's really paying any attention to it because no-one's buying them.

With all that in mind, I think the Xbox OG was under the circumstances the more successful console.

#1 Xbox 360
#2 OG Xbox (Halo 1+2, KOTOR 1+2, Conker, Jade Empire, Panzer Dragoon, Morrowind, Fable, NINJA GAIDEN BLACK!!!!!!)
#3 Xbox Series
#4 Xbox One


Xbox OG was sooo good, even though i got into it many years later, it had so many fantastic games (for me at least) NGB alone wins it for me.

I used to really really like xbox, it's such a shame what has happened this gen, well whatever, Xbox right now feels like a chicken with its head cut off and doesnt know where its running too

Nintendo I think Mario, Zelda and Metroid

Sony I think GoW, Horizon, Ratchet

PC I think Steam, Emulation, Free online and Customization (both software and hardware)

Xbox I think, meh who cares.  

Wrong thread?

Nah, just a build on my original point, the OG xbox had a brand identity, today that really has been lost.  I think that is why the OG killed it in voting. 

Ah, gotcha. :)
Yeah as someone who lived through the OG Xbox era, it wasn't as popular as the PS2 but it definitely had street cred and a positive vibe surrounding it.
