I guess I'll put in my 2 cents.

I would personally never dock a dogs tail or crop their ears. I couldn't imagine doing it just for looks, now....that's not to say that I don't like the look, but I just wouldn't do it. Angus has a docked tail & the people who did his, did it with a butcher knife can you even imagine?!
I was telling Mark about this & the first thing he said was "He would look stupid with a long tail!". Which I came back with "If none of the others had their tails done, then you wouldn't think that." And he agreed.

I guess it's all just preference. I would still get a breed with altercations, just wouldn't do it.
