Using the Preview app is a treat, with plenty of groovy features under the hood should you care to go deep. Second punishment: by using Acrobat, you’re NOT using Apple’s built-in, elegant, powerful, joy-to-use Preview app.
I wouldn’t make my dog use Acrobat Reader. Every version of Acrobat Reader is misery to use: slow to launch, clumsy to operate, thousands of indecipherable options in the Preferences dialog, and very “un-Mac-like.”
First punishment: Adobe’s punishing your by making you use Acrobat Reader (or Acrobat Reader DC, or Acrobat Reader Pro DC, or maybe an older version of Acrobat Reader). If Acrobat Reader has taken over your PDFs you’re being doubly punished.
