Was the Xbox One a good console in its own right?

I didn't own one at the time, but since picking one up this year I've quite enjoyed it. Haven't fully explored its library yet, but I did enjoy Quantum Break and Gears 4 so far.
The graphics don't seem that much worse than PS4 for me, and it does have most of that gen's best third party titles like Witcher 3, Doom Eternal, Nier Automata, etc.
I'd give it a solid 7/10 personally.
