Checksums are amazing for when you do have a problem, because a scrub will tell you what you lost. Knowing what's been damaged is practically more important then actually fixing it, and ZFS is great at this.
All the Linux alternatives answers to this problem are always "is your data okay? Don't know! It'll be a surprise when you get there".
I know, and personally that is very important for me.
But in practice, it is likely to be less than once in a decade problem - and you should have backups anyway.
So I can understand someone having different priorities. (not me though, data integrity is as important as it gets, I'd gladly pay performance/money for it)
