I'm assuming the OP is talking about swapping Albastache bars onto a bike they already have. Is that right? Let's see the bike!
James at Analog is pointing out that for a lot of riders, changing the bar AND stem works out well more often in his experience. I will concur that the current crop of flared drops are amazing, provided you get them to the right height.
In my experience with Albastache bars, they are awesome, but from a fit perspective I consider them pretty much the same as drop bars. I have a set and run them sometimes on a road bike where I could just as easily run drops. I agree with James that the appeal is a look. For me, the important distinction is that I don't think of Albastache bars as a fix for drop bars. If you have a drop bar bike and you hate riding it because you feel 'hunched over' or 'stretched out', then switching the drop bars for Albastache won't necessarily fix your problems. If you have a drop bar bike that you love riding and fits you perfect but you want to try a different bend, Albastache will likely work and you might prefer the cockpit setup, and you might prefer the looks.
Those are my thoughts/opinions
