On PC they are really good, fast fixing issues and listening to their customers and even interact with them on their oficial forum.
On console it's a different story, ACC is quite bugged , it was on old Gen, and now on new gen it's the same but with some more bugs and issues added
Kunos don't listen to console version customers, don't interact with them on their oficial forum and they don't do the porting and support either.
On old gen version it was 505games for support between customer and developing team ,wich was D3T ldt.
And now it's 505games and untold games in next Gen.
Kunos only send them the updates they make for PC version to porting team "and oversees the port", seems they didn't even try their game before releasing a version/update, cause it's very easy to see the bugs, issues, non working stuff by the customers playing less than an hour and spot the difference between PC version and console.
So, yeah, it's the only "hardcore sim" on consoles, great physics, but game quite "broken" and "bugged" wich for quite some people can be frustrating, support on old gen was a disaster, and i really don't expect to be a big improvement now on next Gen.
Would i recommend it? On PC,no doubt, on console... I can't really recomend it, only for give it a shot now and then between other games.
Really a shame, cause on PC it's really great.
