Yeah, Rockfor Files was popular in the day, and had a brief life in syndication in the early/mid 1980's.
Hill Street as I recall had a more brief life in syndication. I found it to be very realistic, and beautifylly understated and intelligent, all the ssubtle details were there, they didn't beat you over the head with the obvious, they rightly trusted their audience to be able to see what was going on.
My only complaint with Hill Street is that more happened in 2 or 3 episodes to these cops, than probably happened in 20 or 30 years of an actual patrolman's career. But still, a damn good series.
