Yes, both are J Crew and both were my first two pairs of Aldens. TBH, I wear my dark brown more often because they are more versatile. If I had the newer tobacco version that looks more dark-tan with a matted finish, I would wear those more often.
Tough decision, but can't lose. Good luck my friend!
Fwiw, I did stop by the JCrew store at the Rockefeller center in NYC last Sunday and tried on tobacco Aldens. I presume they were from the old stock and looked quite orangy. I couldn't say I liked the look but I keep fingers crossed new stock will look better. They were sold out of their dark brown version, so I couldn't try that one, but I assume it's similar to the Alden's own longwing in dark brown, which I also liked.
The obvious solution would then be then to keep both! With 20% off, the price went down to ~420 and no tax. Given the current delivery estimate, I will think of those as of my Christmas present.
