I prefer Lore and Discipline as well.
Lore is responsible for rituals, rote spells and anything having to do with enchanted items, and I like to get the most out of that.
Discipline, because if you do any offensive evocation, you are going to need to beat your opponents defense roll, and you don't do that with a low skill value.
I also don't really see a value of having conviction higher than discipline. For one, you won't be able to control all the power you could theoretically draw in, so if you use your conviction to its full potential, you are going to need to take backlash almost all the time. And again, if this is something offensive, you might have a mighty powerful spell, but it isn't going to hit, so you wasted it anyway.
But I do tend to even out the lack of conviction with specializations or focus items. Though come to think of it now, those points are probably better spend on control as well.
From a narrative perspective, I like it as well. A wizard to me is basically represented by two components, knowledge and the power to impose his will on the world. To me, that's represented by Lore and Discipline. I understand why conviction is part of the mix as well, but it isn't a priority for me.
