Jeez, dudes - It's not even a contest.

The last one with the snappy music and the emojies bouncing around makes all the others look like amateur hour.  Why are you even having the contest?

If I had to pick one of the others - The fourth one with the British sounding computer voice is probably Okay.  It's gets the data across in a credible way, and has not major negatives.  The first three should be avoided, all have big flaws that will make the coin team look bad.

Dancing emojies - whoever did that is a master - It's national commercial level production value.  No contest.
