The Alta Chutes are made up of at least 6 or eight different lines.
Alta 1 is the most famous and most-skied. The steep portion of A1 is steeper than Tower 3 by perhaps three or four degrees and - in a normal year - A1 chokes down to a slightly narrower crux than Tower 3.
One big difference is that Alta 1 only has one significant obstacle - a small rock rib right at the top of the crux. If you were to fall above the crux of A1, your slide path could take you over that rock but I don't think serious injury would *necessarily* ensue. Tower 3, on the other hand, has a number of trees in the slide path AND it bends left as it drops so a slide potentially takes you into a rock wall on the right. A fall in Tower 3 can have (and definitely has had) much more serious consequences than a fall in Alta 1. So the question of which is more challenging depends a little bit on whether you think a fall is possible.
The other Alta Chutes are Alta 2-A and Alta 2-B, both of which are much narrower and a little steeper than Alta 1; Alta 3, which is more of a steep, tree-dotted face than a specific chute and is also the easiest of the Alta Chutes; and Alta Zero, which is normally closed and when it is open is a very challenging series of connect-the-dots pillows, drops, and slots.
My own preference leans toward the Alta Chutes over Tower 3, but that's just me.
