Thanos' "I hope they remember you" was both the most well-delivered and the most intimidating, no contest IMO.

I used the wrong Your AAAAAAAAHHHH

I can do this all day.

I can do this all day. Don't know why Tell me do you bleed is here.

The hardest choices require the strongest wills.

Men are brave.

I hope they remember you

Best quote among the ones listed here-

"Superman Was Never Real"

The whole extended dialogue is at a different level altogether.

Superman: All this time, I've been living my life the way my father saw it. Righting wrongs for a ghost. Thinking I'm here to do good. Superman was never real – just a dream of a farmer from Kansas.

Lois Lane: That farmer's dream is all some people have. It's all that gives them hope. This means something.

Superman: It did on my world. My world doesn't exist anymore.

I haven't seen anything as good as even these lines in any recent MCU movie.

Both Thanos quotes are the best.

I voted for the Superman quote.

"The hardest choices require the strongest wills."

Toss up Between “I can do this all day” and “I hope they remember you”

This especially is so good because it sounds like something Batman would say as well.

Batman

"Welcome to the planet"

Both thanos quotes > do you bleed > superman was never real > men are brave > results >> i can do this all day

My name is Danny Rand. I'm the Immortal Iron Fist, sworn enemy of the Hand and protector of K'un-Lun.

Dude... have some respect! He is the Immortal Iron Fist, protector of K'un-Lun and sworn enemy of the Hand. Get your order right...

The ONLY true answer

"Here's looking at you kid" and "Frankly my dear, I don't give a damn"

I really liked the, “Men Are Brave.” The timing and delivery makes it great.
