As if those default daggers&spikes had no resemblance, at all....
I like it, though. The only one that makes sense to me. Inquisition is supposed to be the 'neutral' side, on it's own.
I know, right? The other one that makes sense in this respect is the Dragon Maw Throne, which I switched to as soon as I got to Skyhold, but after playing through a couple of judgments and wincing every time my Inquisitor used the frakking teeth as armrests, I switched back to the Inquisition model. By that point I actually had both upgrades, and I realized I liked the look of it a lot better, anyway.
But yeah, I honestly kind of wish they'd put the resources they devoted to Skyhold customization somewhere else, because I can't fathom why in the hell I would use anything other than Inquisition banners, heraldry, etc. The Inquisition is the organization I both lead and represent, so why would I have a banner with anything other than the Inquisition crest on it? Like you said, the whole point is that the Inquisition is its own entity, not beholden to anyone or anything else.
The only exception is the bed, since 1) there is no "Inquisition" bed and 2) that actually would be a matter of personal taste. But that bring up the other issue of what reason do I ever have to go up to my quarters there is literally nothing of import whatsoever up there once I've grabbed the Skyhold upgrade recipes.
