IMHO, I'd go with the terracotta for both cleanliness concerns and appearance. If I decided to order a new 1 or 3 tomorrow, it would be LMB or white with that color. A guy a know with a 135 vert has lemon in his and you can already see wear marks after the first year. To me it's just not a great choice for a daily driver.
