Which do you think was the best trailer?

I would say... "Courage". :)

I to like Courage

The extended look, very emotional and epic.

Love the latest spot with him roaring. Courage is great also. The first official trailer (with Cranston talking). Some money shots for me are the tail whipping around and his silhouette in the smoke, his spines reflections in the school bus, as well as him getting pelted by gun/tank fire at the GG Bridge.

Of course, the mother of all teasers/trailers was the proof of concept (Oppenheimer monologue) from SDCC '12, which wasn't officially released. That would have been a fantastic teaser to show publicly.

They've all been great.

The extended look, I love the emotional moment and the roar at the end.

International trailer for me, I like the music and sounds being put in there

can i say wondercon footage but if not internatinal trailer 

The ComicCon concept trailer from 2012. It set a basis for Gfans on what to expect, and it captured the overall terror that Godzilla induces.

The first official teaser trailer. I'm a little sad that the tone from that one is completely gone.

But after that trailer I would say my two fan made ones ;D

The SDCC 2012 trailer.

It sends literal chills down my spine everytime I see it.

The international trailer was the best of all.

For me the first teaser with the halo jump was one of the best, because it is so atmospheric and scary, the music and so on.

And at the end Godzilla rising out of the destroyed city!

The first time I've heard the new (old) Godzilla Roar <3
