Much much less grind
Combat
I can't stand the tired, old cooldown driven combat of most MMOs. So ESO is a big improvement but not perfect. Animation cancelling and synergies (press x is banal) are disappointing but bearable.
Visual Style
I don't love everything in this department - eg. the hideous Telvanni tumor towers and Summerset's generic fantasy human architecture and clothing - but there are lots of clothing sets I do love and its architecture is generally at least decent.
True to the single player games, its style is more realistic and immersive than other games which tend to be cartoony or too flashy and intricate tailored for Asian audiences. Which ESO does a bit but not too much, eg. contrast the base game's dunmer styles with Morrowind's.
The outfit system is great in design, but priced to exclude. This is a massive shame IMO. ESO would be much more enjoyable to me if like other games, you had multiple outfit slots to start with and additional ones weren't outrageously expensive and only for a single character.
Story and Culture
Each zone feels like it has its own culture and the visuals and the stories generally do a great job of expressing that. It makes the solo content feel very immersive.Much much less grind
Getting to 50 is pretty quick and easy but then there's half a year plus of horse feeding and trait research. Not to mention things like motifs, should you actually want to do achievements on multiple characters.
That's one of the major turn offs associated with necromancer for me.
In my opinion...nothing. Has the most lag, clunkiest combat and worst performance.

For me it's the sense or wonder and immersion. I feel like there's parts of game I will never participate in but fact that exists makes world feel Fuller then other games. So guess they do open world the best?
The scale of everything, and that there is something going on everywhere, instead of just at localized key points and cities.
