Maybe somebody can double check my math on this: I just compared the Ruby and Amira base models in a size 48 and size 51. The ONLY differences in geometry between the two bikes is that the Ruby has a longer stem (which would arguably make it less, not more relaxed, but in any event is easily changed) and the Amira has a shorter seat tube by 10mm.
This just further confirms my opinion that a lot of bike manufacturers use words like "relaxed" and "aggressive"--at least when it comes to women's bike--as marketing gimmicks. There is nothing substantive behind those labels. And because they use those labels, LBS employees end up throwing them around, too. Heck, I've worked with LBS employees who insist--even after I show them the respective geometries--that a WSD label means that the bike is substantially different from the unisex/men's version. They often aren't, as others have pointed out in this thread.
So, my advice is this: put the labels aside as you test ride. Is the bike comfortable at every hand position? Do you feel balanced on the bike? Do you like how it handles? Does it feel like an extension of your body or do you feel awkward on it? Remember that you should consider a professional fitting no matter what bike you choose. Changes made during that fitting can influence whether you set the bike up for comfort or speed or a compromise between the two.
Don't convince yourself that you have to ride a WSD bike or that a bike labeled "relaxed" or "aggressive" is what you need. Look at the geometries themselves as you compare one bike to the next. Granted, you may not understand what the numbers mean at first, but look at enough of them, and you might start to see some differences worth considering.
ETA: Please see my later post. I mistakenly compared to current Amira to an older version of the Ruby--when the Ruby was less relaxed than it is now. I apologize for the mistake.
