This.  

US  consumers favor the Xbox brand, more than any other place in the world, simply because Americans like to buy american.
Its not really brand agnostic, it has a more favorable view of xbox than any place else in the world.

The fact that PS4 is outselling the xbox, is simply because its done so much better than the xbox with software/hardware design.
Im pretty sure a xbox that had equal hardware, equal software output, could win the US against a playstation because of this favor.

That however is just not how this gen went.

It needs more than to win 2018, probably needs to win 2019,2020, ect.
Because Nintedo home console systems, generally dont have the legs of playstation home consoles.

When was the last time a nintendo home console went over 130m? (which Im assumeing the PS4 will do)

So basically you are talking about the months of january and febuary..... this one is kinda simple.

look at the NA total for PS4 in 2017 and then do the same for the NS. Now take out january and febuary sales of the PS4. So both have only the months of march to december. and see who wins.

Then again, some will argue that the NS did launch in march after all, and as such its sales will see a launch boost that negates its two missing months of the year when compared to a console that been out for (at the time) over 3+ years.

Then again some will argue that the best way to measure the sales is to take both consoles first 12 months on the market and see which one sold more. But then some will argue that if you did that then it would give the NS an unfair advantage cause its own first year encompasses a launch window and a holiday window where as the PS4 only has a launch window in its own first year.

well their only real rival for the spot didn't launch until 3 months into the year and suffered supply issues for 6 months after that, hardly surprising but a win all the same. Greatness awaits a great many America folks.

The PS3 was saved by being a better machine that sold month-to-month better than the 360 the entire time it was available; resulting in it ultimately selling more units even though it was on the market 1 year less.  On top of that, despite have a brand new CPU and using new disc technology, it didn't fail so horribly like the 360.  The 360 has the distinct advantage of being the being the biggest lemon ever sold in the US.  At almost a 50% failure rate (RROD) it should have had government intervention and a forced recall, but since Microsoft has backdoor deals in Windows for the DOD to use, it didn't happen.  I really don't understand why people were so willing to forgive a machine that was such a POS.  Microsoft PROVED that on top of being a barely competent software company, they sucks balls at engineering.  Sony beats them hands down in engineering, and continues to do so today.   My 60g Launch PS3 only failed just last month - disc drive won't eject.  Still plays, but won't eject anymore.  That's 11.5 years that sucker ran.  My PS2, likewise, is over 15 years old and still kicking (although it stopped playing PS1 discs about a year ago). 

Oh and the, "multiplats ran much better on xbox, especially early one", yeah, that's because they rushed the 360 to the market to get companies to sign contract that REQUIRED they not make the PS3 version better.  IF they hadn't rushed the unit, maybe they could have fixed the RROD issue.  Look at Red Dead Redemption as good example of these contracts that Microsoft had companies sign for games being developed at the beginning of that generation of consoles. It looks like crap on PS3 compared to 360, but by the time Rockstar put out GTA V, they were no longer bound to make the 360 version better, and hence, the PS3 version is far superior.  Microsoft is POS company that likes to use lies and contracts to screw with their competitor.  It's actually a reason that I dislike Nintendo too - they did that to Sega in the 90s, and I will never forget their BS manipulation of the market. 

PS4 the true king

Power isn't subjective at all. The 3000Hp tanbk is more powerful than the 100Hp f1 car though both use their power with different things in mind. The difficulty in tapping that power obviously varies but I've never questioned that did I.

PS3 version also has better lighting. I said that PS3 is more powerful overall but not that it doesn't have its difficulties. The split memory and the hard to code CPU are reasons why third party developers didn't make the most out of it.

Wel, all I'm arguing is that one console had two more months in 2017 than the other so, unless we wall want to wax hypothetical, it's kind of meaningless. 2018, sure. But 2017 had incomplete data.

That's ignoring the massive efforts MS made to increase the product appeal for the 360 by pioneering multiplayer gaming on consoles, building it's online ecosystem, pushing first party franchises that were surging in popularity in the NA market (FPS, TPS) and to top if off, the use of some excellent marketing. Sony certainly dropped the ball, but MS capitalized on the space, had some foresight and tapped in to what was trending on the market.

Now now, hopefully I didn't bring up any undesirable emotions or feelings with my markedly unemotional response.

I was commenting on the use of the word dominating. Sure argue semantics, yes it's winning the point is that it's had an easy ride.

The PS4 might have gigantic appeal in EU and ROTW, but there's definitely plenty of work to do in NA. Try looking at the bigger picture rather than keeping score.
