Been playing on and off since release. 'Finished' the main story of the game within the first month (would have done so sooner if I didn't have potato internet to download the first few patches. I personally didn't run into too many bugs, though playing on a pretty high end system. The game has only gotten better since launch.
The main story itself is pretty short, but there is quite a lot more story telling outside of the main quest. It seems the devs chose to streamline the main story and leave most things not related directly to it for the players to play if they so choose (and if they do a slight bit of digging to find in some cases.)
The few bugs I did experience seem to be mostly gone. Lots of QoL improvements. Not a whole lot in terms of new content as of now unfortunately, however there's still quite a bit to find.
