All my points only apply to single player:
As mentioned here https://forums.civfanatics.com/threads/babylon-eureka-guide-on-some-military-units.664972/ I managed to win on a Island Plates map (or was it Continents & Islands?) on deity, standard speed, only on turn 185. This is good, but in no way very early, and I was save scumming in the first 50 turns for a religion since I had a natural wonder 6 tiles from my capitol I wanted to use for work ethics. I might not be a good player and surely better players would save maybe 15 turns here, but now I doubt my previous expectation, that a sub turn 150 win is guaranteed with babylon on deity standard speed. Once maybe for a pro player, but nothing I could pull of in general.
Nevertheless I share the experience of many here: While there are certainly a few eurekas which (nearly) break balance, it is not in the way, that you can fool around and still win under all conditions. For MP it's surely a ban, but for single player it is simply a very fun and unique approach to the game, which I enjoy a lot.
I do not enjoy games which are imbalanced in their basic game mechanics. This spoils the fun.
But if there is a single civ, which provides me with a unique play style but which I do not have to use, I'm very much fine with it. I trade balance for that: If I want to have a little fun, I can play Babylon. I have absolutely no fear to meet Babylon as an AI opponent in deity. As long as Firaxis does not script a Pike&Shot push or something like that into the AI code, I think the eurekas are too hard to take advantage of. I must admit I have not played games against Babylon AI, but the AI on higher levels has so many bonusses already that they worked similar to Babylon for years now
Civ 6 allows for snowballing and that is the only way to beat the AI on higher levels. The fun thing is that there are so many ways to do it and each game is different.
