Hmm, I admit comparing two different dungeons makes it a little invalid. But I stand with my point that I've never met a good strength tank before, meaning that I don't like the thought of not so high level people (like myself) running around like that. The only time I had a similar experiance was with a really undergeared tank (The Vault).
With "easier to heal" I'm not talking about keeping them at full health at all times it's just esier to predict the damage, and only when I can predict that the tank doesn't die in the next 3 seconds can I dps as well, which is nice.
I actually don't see many strength tanks though, it would be cool to get one that makes me go "Well, that was a fun run!" some day. With tanks that have mostly Vit stuff I just assume they have their points in strength. At least that's what I do.
I find it funny that people get so defensive about this, all three things are possible and this is really just an "my opinion is the only one that matters" discussion.
