Usually depends on handling and management, as with most horses.

Yes, I've seen disasters happen here when they set up stable boys that were only used to working with mares and geldings to handle stallions! the poor boys can behave just as nice, the problem is they have different handling "specifications"... maybe we should start ordering them with an instructions manual! I remmember It took me quite some time to get used to comunicating with my naughty stallion and when I did all geldings and mares got wary of me wilst my stallion couldn't be a happier giant pup! I was like, HUH? then had to learn to deal with mares and geldings all over...

and unfostunately this is not a portuguese mastery... wish it was! I know yards here that use lots of stallions in school but keep them confined all the time as they state them to be "VERY DANGEROUS". So they're allowed to be squished between leg and hand, under a roof and 4 walls or between 3 walls and door with manger getting slapped in the face everytime they poke out so sniff passers by...
