I agree that the quality of the cut and tailoring really stands out when you compare the light Burberry to the BB trench. It makes your figure look absolutely perfect!
Am I right in assuming that this would be your most expensive trench coat by far? If so, I would go with the classic honey color. For some reason I like the color of the one in 9, 10 & 11 better than the leather trimmed one in 6, 7 & 8. Are they different shades IRL? You often have lively, colorful outfits underneath (to say nothing of Miss Scarlet) so I think the honey would provide a better backdrop, especially when worn open.
I do love the wine colored plaid trench with your complexion. Love! And I agree that it's a better color on you, but I'm not sure it's the most practical for something that you will have for a Very Long Time. It's a very memorable pattern and color and you may tire of it, or even feel that it "dates" your trench to F/W 2013--since it's such a big wine/burgundy year.
Rae has a great point though. It's not like you are "pressed" to buy a trench right now. You have some great ones and it's not like Burberry are going to stop making fab trench coats anytime soon.
