Seriously? IMHO, WoW Vanilla was WAY better than Everquest. It was more accessible, more polished, less buggy, better graphics, less laggy etc. You can still play the old Everquest for free, see Project1999. And you will see, the game is terrible.

There are reasons why Everquest died when WoW Vanilla came out.
And WoW Vanilla was never a real story game. It is more comparable to D&D. You have a world and you play some campaigns in it. Chris Metzen, the inventor of the Warcraft universe is a tabletop guy. You could play the game and follow the stories in it without the books. With the books you got some background informations. But the books were not necessary to understand what is going on in the game. This problem has the current WoW. It is not possible to figure out why some things happen and why the pro-/antagonists act like they act without the books. I guess, the current devs tried to make a transition from a D&D-like game to a story game. And they failed badly.
