Most people, probably, would agree that steel forks (with steel steerer, naturally) are least likely to break. That's certainly my opinion.
But I have experienced a broken steel steering tube - luckily I was going uphill (rather slowly) when there was a 'click' and no more control of the front wheel!
I don't know how common failures of non steel steerers are, but I've no inclination to make any compromise on safety in this department.
