I'd lean towards Disc Priest or a Monk
Tbh whilst sure disc might be #1 hps followed by a pally or monk and shamans might be last, a group needs a decent healer balance. discs might have incredible hps because they negate the damage before it happens but they lack the throughput during the oh shit everything is going wrong moments. Shamans however excel at that with there huge amount of cooldowns and will become 1 more in patch 5.4. They have virtually a cooldown for every situation that might need 1 like a cooldown for every rampage on magaera for example + bring good amount of mana via mana tide for the other healers.
Imo in answer to the op the strongest healer currently is paladins. They do have a fair bit of absorbs, some strong heals and decent aoe healing and an all around good healing class.
Disc >>> Monk/Pally/Holy > Druid >>>>>>>>>>>>>>>>>>>>>>> Shaman.
disc > hpally = hpriest > rdruid > monk > shaman
after next patch tho i think it will go
disc > hpally = hpriest = rdruid > monk > shaman
Disc > Rdruid > Hpal > Holy Priest = Monk > Warrior with bandages > Shaman
Something like that ^
Disc is obviously nuts in 10man, they're like half a DPS and do the most healing in the game. Resto Druids are nuts in 10man as well, Wild Growth heals over half the raid. I'm usually tied with my Disc in my 10man, we 2 heal every fight and the only fight he *always* beats me on is Horridon because well, the damage buff is insane with Atonement. Then I always beat him on fights like Council, Tortos, Mag, where there's lots of AoE damage.
Hpals are strong as always, but RDruid AoE healing is just really good so puts them a bit above Paladins.
Holy Priests are strong if they have enough spirit, otherwise they run out of mana instantly, and Monks are pretty good in certain situations but for 10man I'm not sure they're that great.
Shamans are pretty mediocre right now, although our 3rd healer is a Shaman when we needed 3 healers for progression. He was never anywhere near me or the Disc Priest really, but I mean, they cast heal spells, so that's a plus.
5.4 is still going to most likely be Disc + Paladin + Monk/Druid. Resto shaman could make a come back but most guilds are already set with this healer comp. Even though shaman are getting a pretty nice buff, they just don't bring enough secondary. The big thing that helped during our progression was being able to run 2 disc + 1 mw and beat dps checks by a mile with our healers doing almost 200k dps combined.

disc at the moment is super strong. i'd go with that.

I think most healers are viable right now but disc priests are just way too strong imo.
If you're looking for the strongest/easiest healing class, it's a Disc Priest.
If you're looking for the best utility of a healing class, it's a Paladin. A Monk can also be an assest because they have some powerful abilities and they are treated as melee by the game, so not targeted by range specific mechanics but don't actually need to stand in melee. Druids can also have some pretty nice utility with Symbiosis.
If you want a real challenge and to show just how good a player you are, Holy Priest or Shaman.
Our guild runs two heroic 10 mans. One group three heals with a Disc priest, Druid, and Paladin. The other group two heals the same fights with a Holy Priest and Shaman.
