Good list, although I haven't seen 6 to 10 but 2 to 5 are on my list too.
Here's mine, not really a top ten but my fave episodes I can think of right now, I'm sure I'm forgetting several, one curious thing is I couldn't think of a single episode of a Netflix show even though there are several series I love.
Game of Thrones - Winds of winter - 610
A wonderful hour or so of tv from start to finish.
Also like to add my fave payoff from the show, the reveal of Hodor's name from The Door.
Breaking Bad - Ozymandias - 514
I have nothing to add here, so I'll just name my other fave intense moments from the series, the ending of Crawl Space and the parking lot scene from One Minute.
Twin Peaks - Gotta light? - 308
This is probably the greatest achievement on TV of this decade, not only episode 8 but the whole thing.
Fargo - A Fox, a Rabbit, and a Cabbage - 109
Everyone shines on this episode, it should go hand in hand with episode 8 where Lester escapes justice and has a great life but he just can't help himself.
Leftovers - International Assassin - 208
I was very close to give up on this series when S1 ended, not that it wasn't good but there were characters that bored me, then S2 and S3 were incredible and so we got this gem of an episode.
Watchmen - A God walks into Abar - 108
Just a wonderful episode from start to finish, everything worked for me, acting, music, editing, the way they explain how Dr. Manhattan experiences time, Regina King was amazing.
Episode 6 was a very close call as one of the best and actually 7 too.
Hannibal - Antipasto - 301
It seems almost wrong that my episode doesn't have Will Graham in it, but this season opener was just wonderful.
Mizumono, the finale of S2 is also a fave of mine, it sealed a great season from start to finish.
The Knick - Get the rope - 107
IMO as perfect as any series can be.
The Jinx - "What the Hell Did I Do?" - 106
Is it valid to put a doc? This final episode has one of the greatest endings I have seen, and that's why is on this list.
Westworld - The Passenger - 210
One of the most ambitious series ever created really came together with its second season, all women here are a delight to see and this finale delivers, can't wait for S3.
Big Little Lies - You get what you need - 107
And its mystery is solved, the editing on this episode is perfect.
Veep - Crate - 309
Selina goes from being completely destroyed by her own stupid staff to later in the episode become the next POTUS, and S3 finale New Hampshire is just as good.
Fleabag - Episode 6 - 106
This finale took me by surprise, one of the few times that something lives up to the high expectations it gathered, also season two opener is wonderful.
