There's no comparison with Carmina, which is a clear step up for roughly the same amount of money. It's a tough comparison with Meermin because Meermin is so hit and miss with its quality control and has awful customer service. When it comes to Meermin vs. AE I always try to pick AE because I know AE's great customer service will take care of any problems with the shoes.
I had to return my McAllisters (only paid $230) because I bought the wrong size, and they didn't carry a 9E. $350 with another 8% tax is putting it close to Carmina territory, but I really want those burgundy Mcallisters back (or this case, the upgraded Jeffersons).
Tough choices once it hits around the all-in $400 mark.
You also need to factor in that you cannot try on Carmina before ordering from Spain, so if the shoe does not fit you're probably trying to flip it on EBay. As an E width for AE, it may be more of a gamble for you than it was for me as I am a D width for AE's 5 last and found the Forest last to be pretty comparable and the Rain last to be slightly wider but still comfortable. My Inca last shoes are probably close to the equivalent of an AE E width. As part of your analysis, there is something to be said for being able to try on a shoe before purchasing, which might counsel for AE or relying upon one of the Carmina vendors (Gentlemens' Footwear or Skoaktiebolaget) to help you dial in your size before ordering.
