I went through two PS1s (laser failed in the first one), two PS2s (again, laser failed), a PS3 (YLOD), and my PS4 is having a hard time booting up. My original PS1 and PS2 lasted two years, were in well-ventilated areas. I did use them a lot. PS3 was also in a well-ventilated area but it did last a few years as it was a launch 60GB PS3. PS4 is a launch year model.

My 360 failed after 1 year from the E74 error, which was the 360's second major design defect, and mine failed about six months before Microsoft finally acknowledged the E74 was a problem and started fixing them for free. They wanted to charge me $150 for repairs. 

The only console maker whose consoles I have never had fail on me were Nintendo's consoles. Other than the NES's issues with its cartridge slot, which would still work if you adjusted the cartridge, I've never had a Nintendo console fail on me, not even the optical disc-based ones. And of course the drift on the Joycons, LOL, but those have outlasted some other controllers I've had.

Already demonstrated how faulty it is using controllers to assert that a console is a "spiritual successor" to another console.

I.E. Playstation 5 uses ergonomics clearly inspired by the Xbox One, doesn't mean the Playstation 5 is the spiritual successor to the Xbox One.

Or the Switch Pro controller is also inspired by the Xbox controller, doesn't mean the Switch is a spiritual successor to the Xbox.

Every company takes design cues from another... A good idea is simply a good idea... Again, Sega wasn't the first company to have ports on the controller for expandability, the Nintendo 64 did it a whole generation earlier.

As for the ABXY arrangement, there is only so many ways you can take that approach... And is an argument that is questionable at best.

Six-face buttons has existed for a long time... Again. The Nintendo 64 did it with it's 4-C button layout plus A+B buttons, doesn't mean the Dreamcast was the spiritual successor to the Nintendo 64.
The Xbox used the secondary white/black buttons mostly as start/select for the most part.

That is because even if one hardware is better or have more features what you are going to remember is what you played on it.

6 buttons was already present on the Genesis/MegaDrive, I think the model after street fighter II and the turbo controller. Perhaps even console prior to it had some 6 button controller as well.

I will say it one last time. Microsoft directly used Dreamcast controllers to model the duke after. This is not a fan comment. This is fact. The controller was by MS own admission in the book Opening the Xbox they used Dreamcast as a focus test console. They modeled the controller after Dreamcast, tho the duke ended up larger than they wanted due to the board. Why it had 2 memory card slots..one of them was going to be for an Xbox VMU that was scrapped. They used the same colored buttons and the same layout. The Xbox controller was directly the successor to the DC controller. Also like the DC the online headset plugged into it and yes DC had a headset that plugged into the controller. Not just the mic. I own it. The DC controller was evolved from the Saturn 3D pad.

Not really. DC had that same PC vibe with online browser support, keyboard support, and more importantly games like Quake 3 Arena and Unreal Tournament which both ran fantastic on DC and had amazing online play for 56k machines. In the case of Quake 3 you could even play with PC users and let them slaughter you with their broadband connections.

There were other PC ports that ran well, like Rainbow Six, etc. Plus titles like Phantasy Star Online felt like something you'd only previously been able to play on a PC. The issue was the DC just didn't last long enough. The Xbox didn't differ from the DC in terms of feeling like a PC squeezed into a console box, it just continued where the DC left off. IIRC the DC was discontinued before the Xbox even launched.

Right. We all know the OG Xbox was the strongest back then, but man the Dreamcast was just stellar. I think Sega can compete if they re-entered the console business again.

It's worth noting the Xbox is 3 years newer than Dreamcast in terms of hardware so naturally its more powerful, but DC was an absolute beast for its time and could hold its own against the PS2 graphically despite releasing 2 years earlier.

The DC couldn't really hold its own against the PS2 graphically, and it launched 1 year and 4 months earlier.

It couldn't quite match PS2 graphically but I feel it could hold its own as in remaining respectably close, not that many PS2 games look better than Soul Calibur IMHO.
