Those are the only other 2 I know of off the top of my head with the RvR PvP system. Both DAoC and ESO are better games than the two you mentioned on the PvP side in my opinion, but that's going to vary from person to person.
Currently Playing: ESO and FFXIV Have played: You name it If you mention rose tinted glasses, you better be referring to Mitch Hedberg.
GW2. I know it's instanced, but the instance is so big you won't notice it isn't open world. It's flat out the best RvR PvP experience right now. Though I'd keep an eye out for Camelot Unchained though.
Not exactly open world but maybe the secret world would fit your wants... huge pop instanced area with illuminati vs Templar vs the Chinese type faction... plus it's b2p

Well.. as you mentioned good. That would be DAoC. And more or less DAoC alone. (can't say enough about ESO.. so maybe you can add that, too)
As for not good and not 3 factions.
You could add Aion, World of Warcraft(yeah they got that too.. and yeah it sucked), and a lot of other not so good pvp games.
Since you are asking for pvp mmo, and not mmorpg....
PlanetSide 2
Planetside 2 if you don't mind FPS gameplay.
SWTOR Referral Link
Free Goodies for new or returning players.

Planetside1/2 is more of an FPS.
Other RvR open PvP fantasy mmos closer to GW2/Regnum's genre are the following:
12 Sky 2
9 Dragons
DAOC (Try the freeshard if u like)
Asherons Call (pay $10 once, play forever, besides Regnum i recommend this one)
RF Online
Conquer Online
Shadowbane Emu
I would skip ESO. It is bound to still have huge pvp imbalances for some years.
ESO or Planetside 2.
aand GW2 does not have factions
