Hey if only other people could discover that! lol Honestly my apbt pose their own hard ships with DA and PR issues but really when its broken down even for an experienced owner my Malinois are 10 times harder to own than my apbt. Some dogs just require more out of their owner.
My wheaten terrier and rat terrier were a damned breeze when compared to my apbt and my malinois. Of course the wheaten is impossible, literally, to train and the rat terrier has stranger issues but really? meh. They live with my parents who occasionally walk them, free feed, and pet them nightly. I could probably do that with my elder apbt but with my malinois? even when they're elder? Ha! With a border collie, jrt, etc etc? doubtful.
Also the wheaten and my apbt are very human tolerant. One of my mals is and one isn't, I couldn't allow people to just walk in my house easy breezey if I owned a guardian breed. My female mal needs some work but for the most part she's accepting which is the way I like it. Life isn't nearly as easy if you have to pen up your dog every time you have company.
I think human aggression is also much harder for JQP than high prey drive and dog v dog issues. Which makes any predisposed human intolerant breed a much harder for first time owner breed.
Last I think any breed prone to obsessive compulsive issues is harder for the average pet owner/first time owner.
A good, well bred, lab or golden or apbt is actually a really good entry level/basic pet owner dog imo. As well as many good old mongrels.
While every breed has its extremes and its exceptions to the rule its smart to hedge your bets and your bets best advantage is knowing that the higher the drive, higher the energy, and lower the tolerance the dog is the less likely it will be a good first time owner breed.
