How is vaikuntha different from SwargLoka

I am assuming since swarglok is still part of the rebirth cycle, it's were the souls go to get fruits of their punya and satisfy their materialistic desires. But lot of vaishnava sects consider moksha(liberation from rebirth cycle) as souls reaching vaikuntha. So what really do souls do there? I am assuming there is no lust or any materialistic desires that are satisfied in vaikuntha, since reaching their is considered moksha that is liberation from such desires. I am not of the intention to offend any of my fellow vaishnava , please pardon my ignorance🙏☺️
