Vegas Pro 16 vs Photostory Deluxe

Hello,
I’m quite a beginner in video editing, so there’s my question: Just wanted to ask which software is better for my purpose: Vegas Pro 16 or Photostory Deluxe both by Magic to make a semi- professional “movie” (more a slideshow). I have mostly Photos, but just a few videos. But Photostory deluxe just export it at HD, but on the other hand is more specialised for my purpose, I think. What do you recommend?
