I feel a bit the same as you I mean I enjoy Breaking Bad but it's not the top 3 for me The Sopranos I thought was good but I got bored at the end of season 3 and never carry on with it I've never seen the wire
I actually prefer British drama to American even though I've lived in Australia a long time I never watch Australian shows I like things like the night manager and the British version of House of Cards things like that .....Happy Valley is brilliant in my opinion but my favourite all time drama show series would be the Prisoner with Patrick mcgoohan probably the most forward thinking and inventive show ever made absolutely brilliant in its conception to take over an entire Village/town for a TV show was probably a first.
The Prisoner in my list would probably be equal number 1 with Tinker Tailor Soldier Spy starring Alec Guinness a monumentally great series
