Nothing much different - just calmer in general, though boys can be rough with each other. At least you don't have any females to stir them up! Their crow can be a bit annoying (some are louder, some are quieter) but if they are happy they won't crow much. They are sweet birds.
They do have some small scuffles, but they only last a few seconds before they both stop to preen, and they have to get within a certain radious of each-other to even start it, and it isn't that large. It is rather amusing. I do have female Chinese Painted Quail, but they luckily don't seem to trigger anything. The wild-morph male is rather noisy, as he is getting used to his new home, but I enjoy the crowing so far.

And they are super sweet, though the gold one is a little nippy at times and doesn't always want a fuss... I didn't know they sounded like a baby panda sneezing when they attacked you, I about died from cuteness and the pecking didn't even hurt.
I let them run about in the kitchen my chickens were in, though the chickens are very healthy birds I raised almost all of them barring 2 from eggs and so I was not too worried. And my goodness, they are fearless little buggers! They didn't have a care in the world about the chickens even as some youngsters stalked them and tried to nip at their toes, due to them being different... They'd just take 3 steps away from the curious hen and start preening or pecking about.
It didn't take long for the chickens to lose interest in the quail and the wild-type one was even eating with the chickens from the food tray, literally between a hen's legs! And they have their own food and water bowls they could eat and drink from, but they wanted to hang out with the chickens instead.
