Toucans, or at least the kind we had, have serrated beaks, so in addition to the clamping force, they can tear your flesh while they’re at it.
I do believe they have less bite force than most macaws, but they’re also less docile than most macaws also. Macaws rarely use anywhere near their full power when biting things or people.
Birds live really, really, really long lives, and require more emotional support than any animal I know of. Unless you have children who are okay with you willing the bird to them, and can at least spend a full time job worth of time with the bird every week, don’t get one. I mean, seriously, if the bird doesn’t live on your shoulder during your every waking hour, you are emotionally abusing and traumatizing that bird. They’re far more intelligent and social beings than most people give them credit for. They should not live in cages.
