CON: They scare away perfectly nice people.

Giant breed dogs often get judged as intimidating due to their size. I've had drive-thru workers who are afraid to pass me my food through the window because Luna and Argos were in the back, despite the fact that the worst thing the worker would have experienced was a bucket of drool. Pizza delivery men, UPS delivery workers, and neighbors have all been stricken by fear when I have opened the door, holding back Luna and Argos by their collars to prevent an assault of licking and cuddling.

PRO: You can play rough(er).

Sometimes it's fun to be able to use all of your strength in a tug of war game or get knocked down when your dog runs at you full speed. Playing with the Pyrs is definitely easier than playing with my Chihuahua because I don't have to be careful when it comes to my own strength hurting them. My best friend's Great Dane loves to play rough with her and her family and, considering he's bigger than most of them, it makes for a pretty epic tussle.

CON: They often don't know their own strength.

This goes hand in hand with giant dogs not knowing they're giant. My giant dogs would never intentionally hurt me, but considering they weigh more than me, twice as much as me when being walked together, accidents do happen. Argos' Pyr-paw (the breed's infamous act of placing one paw on you when wanting attention) has resulted in a whack to the face or a scrape on my arm. The other day, Luna and Argos saw a stray cat while on their walk, and both sprinted full speed toward it. Me, being unmoving and less powerful than 200 pounds of pure muscle, got yanked off my feet and dragged a foot on the ground before they realized what they'd done and came to check on me.

However, I will note here that giant dogs, Pyrenees and Great Danes in personal experience, are often hyper-sensitive to the small size of children. When a child is in the room, my Pyrs automatically calm down and will let that child do almost anything to them without reaction.
