I'm sorta biased but in terms of actually completing things..
I'd say a bad tank/good healer will win out. The healer can overcome the agro loss and bad tank with healing through it. The dps will eventually take down the healer's aggro'd mobs. They should anyway.
I'm not sure how well a good tank and bad healer will hold out when the bad healer can't heal well and everyone is dying. The tank would just die faster with keeping all the hate while potentially trying to heal himself or mitigate the damage dealt to him.
As BLM I like BOTH good heals and good tanks.
As PLD I like good heals because I think I'm a bad tank.
... My CNJ and ACN are only lvl16 so I can't comment on that.
