What are the benefits or upsides of Scientology?

There’s been lots of discussions on why Scientology is a sham and/or dangerous. From what I know of it, it seems kinda nutso. So I’m wondering, is there anyone on here with an opposing viewpoint (as in, a positive one) who would like to shed some light on why someone would follow this line of beliefs?

I mean this as a serious question, by the way.
