Oh, come now. I use mods to ensure I have fun with the game.... mods that help me avoid the grinding. Besides, this game shows me it's alive when compared to DAI. An UnFun game makes any other working game better. DAI, for many is UnFun, especially when I was given the impression by ML & Co, that it would be better that DAO+DA2 by retaining the best of the old and adding improvements.... Ha!
So, to me, Skyrim is better in many ways. DAI is better in the voice acting department. I'd say even in the graphics department but DAI is worse in companion pathing. But far worse in the modding capability. I'm not going to discuss tactics, camera, UI, inventory, KB&M, key bindings ... etc.
I'm sure you can come up with a few Skyrim is better than DAI features, if you work hard at it.. 
"I use mods to ensure I have fun with it" - what were you doing with it before the mods? Are you saying it was fun before you modded the crap out of it?
As to better features... nope. Unmodded, the combat is crap. The UI is crap. 'Arrow to the knee' a million times over. Chased to the edge of the world if you inadvertently kill a chicken. Everyone is orange if they aren't grey. No one looks like they bathe. Ever. The storyline is insipidly stupid and the ending about as exciting as DA:I's and the side quests are dull and uninspired. A guy with eighty pounds of armor sneaks up and picks a pocket in a busy marketplace and no one notices him crab-walking by. Sure. Immersion. Woo-hoo. "Look out! Here comes an incredibly stiff dragon! Never mind, it's glitched and hurtled away over that mountain for no particular reason. Hoorah for Dova the Explorer!"
Nah.
I've played (and modded) Skyrim (or else I wouldn't criticize it), and frankly, I'm thinking a lot of folks have the same nostalgia glasses on for that game as they do for DA:O. The game we were sold - the immensely buggy pile of bullpuckey it was on release, and not the heavily, heavily modified versions that are enabled after (and what people are actually talking about, incidentally) - that was not a good game. That it required a dragon-crap-sized load of mods to be worth the playing does not speak highly of it. Modded to crap it might be a decent game. But - putting racing stripes and a slightly larger motor on a lawnmower and having a supermodel with actual boob physics to drive it doesn't make it a showroom-worthy Bugatti. It's still just a pretty, slightly faster lawnmower with a top-heavy tart on it.
Anything that alters it so fundamentally is a different game. That game is superior, sure. But it ain't Skyrim.
Skyrim is better for many because you've all changed it from what it was into something you liked. That says to me that Skyrim on its own wasn't that great. You had to go and find pounds of lipstick to slather on the Dovapig before it was worth the dancin' with.
Sorry. Still not points in its favour. Not to me, at any rate. Sixty bucks for something I have to spend days and days altering myself for it to eventually be worth my time? I must be the only person who sees the problem with this. IMO it enables devs to be even lazier. The fans fix it. The fans create content. The fans, the fans, the fans. Not the people being paid to do it. The fans. The devs sit back and travel the path of least resistance and the fans fix it and the devs get the accolades they do not deserve. The next game gets slapped together and this parasitic roundabout keeps going and going.
Still, crapping out this mess of a Dragon Age game and ass-draggingly-trudging belatedly in a half-hearted attempt to make it playable six months from now does show a kind of integrity, even if they too are trying to rope the fans into help fix it.
Still doesn't make Skyrim a better game.
