Just skimming through the article you posted, it says trials with a similar treatment resulted in one patient dying from a massive immune response and two other got cancer. Sounds like it relies on a virus to deliver the DNA, but I didn't read too carefully, so maybe CRISPR will turn out to have fewer side effects or a greater success rate. I'm pretty sure one of the up-sides to CRISPR is compared to other gene-editing techniques it's relatively cheap, which is always a plus.

The death and cancers mentioned over there were from gene therapy trials in general, not the specific study in the link.
