Until I realized it wasn't the fault of the breeds, I disliked QH's and Appy's for years because I grew up being an Arab and Morgan person, for which I paid heavily from my QH & Appy trail riding buds - lollol
My best babysitter ever is my 26 yr old Arab that I rescued 19+ years ago. He's been a baby and toddlers horse since he was well enough to put someone on his back.
He came to me starving and with an injured vertebra so I could never ride him. However, his little 13.3H self quickly became a lesson horse for children ten and under.
As has been stated, Arabs are loyal to their death but one has to earn that loyalty with an Arab. They are intelligent to their own un-doing and greatly mis-understood; just like Rottweilers, Dobermans and Pit Bulls
