It still starts it's effects within an hour, and this slower "start up" time gives it less of a "rush" that people like about xanax for example.
The longer lasting part is IMO better too, I have bad anxiety (and potentially on the spectrum), and knowing that I can take .25 or .5 (I'm prescribed .5) and get through the stress of something new or any other activity without a full on panic attack helps me out a lot. Just as an example, the idea of going shopping at the mall with a new friend (I'm in college btw) is already making me anxious as I write this(And this is just an example!).
Xanax seems like it'd be less helpful if I'm going to be hanging out for a while.
