The only “contemporary “stereo records that I love in past was by Rafael Kubelik with Fischer-Dieskau, Giacomotti and Bergonzi.  The orchestral part of that La Scala play is amassing. Still, in my view it is not the best Rigoletto and mono recordings of Rigoletto  way more interesting.  There was a production in 1956 with Fausta Cleva led Metropolitan and Warren, Tucker, Ellis and Tozzi. It was extremely good – no stereo recording stay even close. And of cause there was the Rigoletto of Rigolettos: the Tullio Serafin leading La Scala and “his” offensive cast of Callas, Gobbi, Stefano etc… That Rigoletto I can listen 3 times on a row… BTW, in contrary to many other classical operas, the recent CD re-mastering of that Serafin’s Rigoletto is better then what was done in 70s-90s.

Tthere was 3-4 years ago a Rigoletto broadcast from MET with Anna Netrebko, Nancy Fabiola Herrera, Rolando Villazon, Carlo Guelfi, Eric Halfvarson.  Conductor was Asher Fisch. It was extremely good. I even managed to record the part of second and third act (go home late) – it was very very very good. The troops was not as able as some stat-singers from past but they really-really “tried” as good as they could - and you can clearly hear it and it made the performance “very special”. I can post a fragment from it…
