It could be considered better in some ways for a lot of people. It has a proper D-Pad, it fits in your pocket, and it's $100 cheaper.
Every way besides price of course.
Nintendo has yet to officially make one, but there are third party Joy-Cons with d-pad if you really need it, and from what I can tell it looks bigger than the N3DS XL which only barely fits into my pocket, but eh technically it's still more portable regardless. Even the smallest insignificance can be a reason I know, that's why I'll be interested in hearing from those who prefer it over the regular.
