Definitely the multi without the teal. Let us see your final design.

Ya know....I just went back and looked. Maybe the teal as first border would be just fine. I think the issue here is you showed such a small portion of the double border. I am sure you have already gotten started, but if you haven't, it would be nice to see a pic of a larger portion of the quilt with the two suggested borders. It is really too hard to tell. Sort of like if you were in your own sewing room trying to make the decision by looking at it from 8" away to decide!
