Why do Christians want to go to heaven?

The very few descriptions of heaven we get are basically angels just praising God for all of eternity, a fate so horrible that supposedly a third of all the angels rebelled and decided hell would be better. We are talking about beings that are supposedly superior to humans, and that also didn't have to go through a whole test just to get to heaven. Legit like 95% of all issues with christian doctine? These angels never had to wrestle with it, or think about it. They just got to be in heaven.

They don't have to deal with loved ones burning in hell, they don't have to deal with the fact God commanded genocides and ethnic cleansings or wiped out the earth with a flood and said whoops! I regret that! Never gonna do it again... totally! They don't have to deal with any problem anyone could raise with Christianity. All they had to deal with was what supposedly everyone should want and he aiming for. Life in heaven. And a third of all the beings that are "better" than humans couldn't stand it? A third of these beings who are surely more patient, more just, more able to deal with annoyances, and more likely to not be bothered by life in heaven as they were created with the intention of serving roles in heaven, didn't like it. Why the hell should I even think I would like heaven?
