I always find questions like this hard to answer.
Journey as an example, I find to be an incredibly easy dog. She's busy and she's energetic, yes, but she is also quite content going multiple days without much in the way of exercise and is just a really good house dog. Never has been destructive, is quiet, sleeps and cuddles... just really easy. She's also super easy to train because she's so motivated by food or play and also just loves to make me happy.
However, with another person? Journey could be a nightmare. She's easily over stimulated, if there are things moving (particularly other dogs), she wants to chase and will bark in frustration if she can't and needs a lot of practice with focusing and impulse control. She needs a lot of people time, whether it's just sitting and snuggling or actually doing something. For as easy as I find her to be, I know that she would actually most likely not make a very easy family pet for a less dog savvy person. She certainly could do it, but she'd probably drive people crazy with her business or I could see a non dog person accidentally creating an activity craving, "go, go, go" Journey by accident. Because she will go for hours and hours on end, and a lot of people believe that if a dog will do that, that they need that much, and it's not true. So yeah, in short, I think Journ could be a bit of an annoying, neurotic dog with the average family. Pretty much like most of the Aussies I meet with people who didn't know what they were getting into haha.
On the same token, I find the Dobermans to be somewhat difficult, when in reality, I think a regular dog family would love them and not see a problem at all in most aspects. I just find them overly needy, in your face in a pushy way, noisy (always complaining about something), not very people pleasing, etc. But the average pet person looking for a laid back family dog? Those things probably wouldn't bug them. As long as they could teach them to sit and stay with a few treats, they'd be set haha. They sleep most of the day, barely need any exercise (at this point in their lives), are quiet, aloof but friendly with visitors in the home... lots of easy things. But yet I still find them to be a lot of dog somehow. Just a clash in our personalities I guess.
With that said, I find that dog people often do frown upon the term "easy dog" too. People always talk about how naughty and bad their puppies or dogs are in the classes we take, and I'm just over in the corner like "my puppy is an angel" lol, and then they think she must be boring. When in actual fact she's not. Dog people seem to like to hear about how naughty peoples' dogs are. And then pet people want to hear about everyone's perfect, good, impeccably mannered dogs.
