When they're first released there tends to be a lot of issues and gaps. Subsequent expansions tend to fill out those gaps. The expansions for Civ4 added a lot, for example.
I played at least 100 hours of Civ6 but honestly it didn't grab me. One issue (and this is a general issue with Civ games) is I tended to avoid war because it would totally bog down. A protracted war (if, say, you're going for a Domination victory) might take 3 full days to play (ignoring early Domination wins).
Anyway, I haven't played a ton of Civ6 since the expansions so can't comment on the current state. I know there are a few diehard fans online who stick to Civ5. I played less of Civ5 so have no opinion on 5 vs 6.
Civ6 does have some weirdness I wish it didn't (and maybe it's been fixed?). For example the price for creating districts is determined when you first create them so it's optimal to create them all early, cancel production and then build them much later to lock in a low price. I don't like this kind of micro-optimization being rewarded (even necessaary on higher difficulty levels).
I really enjoyed Beyond the Sword - particularly the random events and the choices you could make. Sadly, I've never managed to find a mod that made them more frequent or a mod for Civ V that introduced the concept without additional complexity around the mechanic. I forget the name of it, but one of the Civ V mods added random events but you had to make magistrates and save up points to be able to make a decision.
