How common is it for Christians to see God and Jesus as distinct individuals, versus being the same person?

I was raised interdenominational. When I was little, I noticed that some people said Jesus was God, but others said he was the 'Son of God', aka a distinct person. I asked my mother about this, which was correct. She told me that some believed one, and some believed the other, but no one knew who was right. That's true interdenominational right there. Due to the conflicting messages, I ended up with a hybrid view. God and Jesus are distinct, but God and The Holy Spirit are one in the same. To me, Jesus was essentially a high-ranking divine being above angels, second only to God himself. He was divine, and very important, but he was not The Father. He was the sacrifice, and the intermediary between God and humans. I even recall reading an NDE once where a person claimed they saw Jesus debate their case with God, because Jesus knew one thing that God never could; what it was like to be human. Since then though, I've gotten the impression that this is rare. Mormons believe it I know, but people seem to treat this as odd, which always came across as weird to me. Recently I saw a video by The Cynical Historian talking about the history of the Unitarians. They believe that God and Jesus are distinct, but he seemed to talk about them like this was unique to them. Is this not as common as I was lead to believe? The people in my area who have some rather unorthodox beliefs. The prosperity gospel is popular even with sects that aren't normally associated with it. Despite living in a Christian community, I've never met a priest. All churches are fully independent with only a preacher leading the whole operation, even if most of them claim allegiance to one sect or the other. Also, the preacher of my first church may secretly have been a Mormon, seriously (he made a claim once I couldn't find in the bible anywhere, but years later I found out was a distinctly Mormon belief!) Has a poll ever been done? What is the history of the two positions? As for me, I had a lot of other far more odd beliefs than just that. Its clear I was never a run-of-the-mill Christian. Also, I haven't been Christian since my mid teens, so what do I know? Adult Christianity seriously comes across as odd to me. When I was little, it was just short stories and listening to a preacher talk about stuff I couldn't understand. Also, quite a few Christian videos on youtube come across as heretical to me! Such as one showing Jesus creating Adam rather than God.
