Sure, I am very familiar with them -- I actually TAed 18.06 for Strang once upon a time. They're great books too. Which is better is mostly a question of what point of view you're after -- if you want to actually calculate anything, Axler's book is not going to help you, but if you want a more conceptual view of the subject it's best place. If you're really serious about learning linear algebra, you probably want to read both, first Strang, then Axler.
