I watched the finale again

Can't wait for the EMMY's i hope they gonna sweep big time
”I want to keep things as normal as possible, and you not being here is part of that”
All the phone calls in this finale were heartbreaking

, Betty/Don, Peggy/Don ...
I'm gonna miss Roger's wit
"The only thing I got was suitcase! If you're going to yell at me, do it slowly or in English."
Joan:
"Is everything okay?"
Roger:
"For now. But we'll see, I'm getting married."
That "ding!" (I've got an idea!) right as Don cracked a smile followed directly by the Coke commercial was the perfect thematic and comedic punchline to end this series on.

It comes across as both cynical and optimistic at the same time, which is exactly the "ending" Don Draper deserves.
He finally finds "The Real Thing," and naturally he finds a way to advertise it.
