I think it depends a lot on a person's capacity for having a relationship. Some are only able to hold very shallow relationships with other humans, these people are often the most barbaric and violent, and these types are also the kind who accept simple priest-flock religions. A person's ability to interact with humans that doesn't suddenly expand in a spiritual context, their deepest human relationship is likely as deep as their spiritual relationships will be. A lot of people with shallow capabilities go for the "Slave-Master" dynamic because it's the simplest, most archaic type, it's the easiest to access. Because the majority of the planet's population are at this simple state, it'll be the one that you hear of the most, but it's far from the only kind. Your perspective matches the Gnostic view of religion, with the overbearing Ruler/King Demiurge/Jehova that demands worship on threat of death.
Personally, I've found that a "Parental" way of looking at a God to be a lot more mature. What do your parents want for you? To become as successful - if not more - than they are. Parents teach you, discipline you when you absolutely deserve it, let you learn at your own pace, and more than anything they love you. If you apply the As Above So Below law, this would be clearly expressed in our natural human dynamics. If you were fortunate enough to have a good father, you would look up to Mother Earth or Father Sky with the same devotion. God wants the best for you the way your father would, because he wants you to become as powerful as he is.
Bhakti Yoga is much more charged and isn't for me, but I still think it's more beneficial and developed than the slave-master dynamic because it's based on love, rather than submission, this is also the kind of love for God that Sufism teaches. This comes out of a devotion the same way one would feel towards a lover. You love beauty, you love warfare, you love chaos, you love being the outsider in an insane world, you love the mystery that comes from your mortal condition, these Gods that make the world happen do it for you, and you love them as their mortal lover.
In my opinion, the most profound dynamic to have with your creator comes from Esoteric teachings like Nonduality and the Tree of Life. Malkuth is the Omega, Kether is the Alpha, and they are one in the same. This relationship with God is similar to achieving communion with the HGA, one that allows no room for identity or separation, it's a direct experience of eternity, the Dao, of merging with Brahman, etc.
My interaction with the Gods is one of a seed in soil, I am grateful to exist, to grow and thrive off their nourishment. I do not worship my Gods, I am genuinely thankful to them, for all of my suffering, and my pleasure, because without it no development would be able to happen at all.
