RuneScape. It sound ancient but it has made many advances to bring it up to date. Voice overs, new animations, abilities for more active combat, much better music and weekly updates.

I also love the quests. No MMO has ever done quest like RuneScape. They are involved, the dialogue is great and the environments are very varied. The majority of quest actually feel important (except for some of the lower level ones) its none of that "fetch me 10 board hides" bullshit, but actually have a story and unique dialogue. You can't grind on quest, so it gets you to do them for the actual story or unique reward. Some of the newest quests have been some of the most memorable quests in any MMO I have ever played.

Quests is what really keeps me coming back.

Played WoW but not touched it since Cataclysm came out.

Played FFXIV on PS3 and 4 - quite like it an seems casual friendly with harder content for hardcore players as well. But these days I dont want to devout the time it takes to do hardcore so this one I found quite nice to pplay casually.

Played Wildstar - had such potential, but going back to my point about not wanting to devout my life to an MMO (been there and done that with WoW) its NOT causal friendly. You wont get anywhere without dedicating alot of time to it (unless they have changed it since I last played it).

Played SWTOR - Quite a nice game but I didnt get to experience any end game content, I sort of just stopped playing it when I hit the level cap. No particular reason why, I guess I just didnt want to devout the time to it.

Others I had a dabble with, ESO, DCUO, LOTRO - I didnt play any that much though, the only ones I put any real time into were WoW, W* and FFXIV.

EDIT: I nplan to go back to ESO but am waiting for the console release. I much prefer nowadays to play while sitting on the sofa with a big screen.

World of Warcraft

Or

FFXIV if you limit only consoles

But

I'm in love with the hibrid Destiny

Elder Scroll Online, looking forward to the Champion System, Justice System and Spell Crafting updates.

I usually based it on the fluidity of the MMO's pvp gameplay. The first pvp I really enjoyed was the creation of real combos on MMO's which was on Grand Chase. Next I played after it was Dragonica, Dragon Nest Sea, then finally Blade and Soul NA.

As you can see the MMO's I played gets better both in graphics and fluidity in pvp. Although I still love Dragon Nest Sea's pvp than any other MMOs out there right now. Waiting for something like it with more fluidity or improved graphics.

I have some of my own gameplay/strategic videos of Blade and Soul NA here on my own youtube channel if ever you guys are interested. :)

Old School Runescape is where it's at. =)

Likely the only MMO i will ever get into.

Final Fantasy 14 is imo the best MMO out there.

Alot of the newer mmos play like a fighting game, with combos and combo breakers, and heavily pvp focus.

I rather enjoy that in FF14, all you have to do is dodge skill circles on the ground, and make a traditional party, forfill your role and go adventureing into dungeons, and the intire focus is on PVE. Its the best PVE of any mmo on the market.

Everquest is still my favorite, where you need your mate and guild where reputation was very important. now you just auto group auto disband without talk to anyone outside your guild... mmo have become boring to me

I am a console gamer too, however my son prefers Guild Wars (he has 1 and 2) and I was quite impressed with the graphics and gameplay althpough I have never been keen on on-line only games.

From what I have seen of Guild Wars it is buy once and play free, unlike World of Warcraft and Everquest were you pay once for the game and  then you have to  pay the subscription to continue playing. That I personally don't like.

I did at one stage play "Champions of Norrath" which is a PS2 game and is based on Everquest. Even for a PS2 game the graphics were very acceptable and it worked perfectly on my backwards compatible PS3. The network capability (yes it is a PS2 game) worked as well however I could not get find anyone to go adventuring with me since it is an old game and no one was one line. Even in single player I actually liked the game although it really is hack and slash with magic thrown in however  the style of your gameplay is dependent on the character you choose and their attributes you level up.
