I also loved "Broken" so much, just the opening scene with Radiohead's No Surprises while House is struggling with his adiction in the sanatory was sooooo awesome!!! loved "Three stories" from S1; "Alone", first ep. from S4; the two final episodes from S5 (House alucinating of Amber); "Bombshells" from S7 (Cuddys surreal dreams) absolutely fantastic, I could go on and on...
Broken, for me. Hugh's performance was exceptional there. Thing about House is there never was any bad episode, most shows however good have at least one or two you'll probably never watch again, but House its genuinely difficult to pick one standout because they're all so good.
I loved "the down low" season 6 episode 11. Foreman playing the other interns and gets them to take a pay cut to boost foremans salary was genius, and house acting gay to sleep with Wilson's crush was the funniest thing I've seen on TV, especially when Wilson fake proposes to house.
I really like House's Head but I find it hard to see Wilson that sad in Wilson's Heart so I really like the one where House hallucinates a whole episode after he was shot it really surprised me
My favorites are: 1) Three Stories 2) Broken 1-2 3) Wilson's heart 4) House's Head 5) Help Me 6) Now What? 7) Joy 8) Meaning 9) Changes 10) Everybody Dies
