Depends on the individual in my experience.
Unneutered, males are harder to litter train and more likely to spray, and you hear more stories about destructive behaviour due to frustration (hormones + not enough space or things to do). You can neuter them early though, at 12 weeks. Unneutered females are more likely to dig which is very destructive, and often get territorial and can have phantom pregnancies which makes them super territorial and grumpy. Some vets will neuter them from 15 weeks, most like to wait till 6 months old. These are just generalisations though, each bun is different.
Neutered, it more depends on the individual bunny. Neutering is essential.
I would recommend that you get an adult bun if you are worried about destruction etc as with baby buns there is no guarantee how they will turn out and some buns are just horrendous indoors.
