I love both.
I mean on ABC I love:
Desperate Housewives.
AFV.
EM:HE
All My Children.
and on NBC:
The Biggest Loser (I love this show to death).
and it also had these shows: Will & Grace, Friends, The Cosby Show, Diff'rent Strokes, Saved By The Bell.
So as it sits, I love currently what's on ABC, and I love what used to be on NBC.
I think I watch more shows that are on FOX though.
