I vote for @dksart design number 1.

It looks like an interesting conversion starter. With the single tone color it is easy to change it to whatever color someone prefers. It also got enough going on it to make someone go “what is that” and hence the conversion starter.

It also looks rather unique design and won’t be confused with other products on the market. Which fix perfect with the overall brand and it's bold overtone and confidence that EOS has.
