Best 3 Combination?

[guineapig]

I keep seeing people saying Druids are better healers than shaman on these forums.
a) they have the exact same heals

I 100% agree and would not say otherwise. Shaman makes the better choice for a 3 person team if you do not have an enchanter due to slow but there is a little issue with that. In a three person group if your shaman is doing all his buffs on the tank, hasting the tank and slowing the mobs, and healing the tank.. Well that's pretty obscene in the demand department. Sure it could be done but it's extremely inefficient. SO chances are the shaman won't be doing both slow and heals all the time. Honestly the need for slow in Classic is fairly low aside from certain bigger mobs.

shaman are better healers because of slow alone, there isn't much of a debate there

If you have a chanter then you would pick the druid over the shaman due to the overlapping of class abilities (haste, slow, etc.). It all depends on what else the group consists of.

Using both an enchanter and a shaman created a bit of a redundancy in the sense that a good enchanter can slow all incoming mobs and CC without much issue. Then you have your shaman not slowing mobs ever which negates the main advantage you are giving the shaman. It comes down to what you prefer, the big buffs, dog pet and additional source of slow/haste (additional due to enchanter) or the ports, snare, evac, big nukes.
