I worked in game retail during pretty much the entirety of the Xbox 1's generation so this is quite nostalgic for me, but maybe not the way it was intended.
I always thought the Xbox was kinda crap, but I did buy a used one just to play Panzer Dragoon Orta and promptly returned it. Loading times on the Xbox and PS2 were still something of an issue while the Gamecube was pretty good in that regard. Also, the PS2 and Xbox had high defect rates while I think I saw only one defective Gamecube, a trend which seemingly got worse with the 360.
The Xbox hardware was ridiculously huge and heavy, especially in comparison to the PS2 and Gamecube. It may have been the most powerful of the three but not by a huge margin or anything. The fact you had to buy a $50 remote to watch DVDs on it, when you could watch DVDs without anything extra on the PS2 also seemed like quite a rip-off to me. On the plus side you didn't need to buy a memory card, though they did sell them.
The online thing wasn't a draw for me, and I will not pay to play online when I already pay for internet, and since I don't play first person shooters much there has been little (if any) reason for me to pay attention to Microsoft's consoles.
This past generation, I didn't even buy a PS3 until a couple of months ago, and there isn't a single game on the 360 I want that I can't get on the PS3, while the reverse is not true. I expect this trend will continue into next generation since Sony's own internal teams put out great exclusives while Microsoft caters to a type of gamer that isn't me. I couldn't care less about gamer score, achievements, trophies, or whatever you want to call them.
TL;DR I bought a used Xbox 1 just to play Panzer Dragoon Orta, then returned it. Never "jumped in" because Microsoft doesn't cater to my interests in the slightest - and I own close to 700 video games across many consoles.
