Hackamore or bit?

Hello! Today I want to know your thoughts on using bits, some people think they are good, some think they are bad, and some don't know or don't really care. I think that bits can be good if they are used correctly. To do that the rider needs to be light on the hands, and gentle with the horses mouth, when horses are ridden with new ridders who yank the reins they can become hard mouthed, and
not respond to the light touches anymore. This is bad, because then when an experienced person rides this horse, they have to use the cues forcefully. This is a problem with bits, but when used in the right way they can cue your horse to do many different things, and not hurt the horse, but give pressure and direction. We use bits on 1 of our horses, and I would like to train my stud in a bit. All of our other horses are ridden in halters, and my gelding is ridden in a hackamore, he does not like a bit in his mouth. He threw my step dad the only time he was rode in a bit. He has been ridden in a halter  or hack ever since then.
