I haven't tried Homage, but 1872 is a complete waste of money. It's a nice fragrance the like you can easily get for $70 at any perfumery. It's also not particularly lasting. In fact the old Crown Perfumery Sandringham (still available at Parfums Raffy) - Crown is the house that Christian bought and then liquidated and on which his current perfumes are based in look and style - is a much better fragrance.
Homage, if Luca Turin can be believed (and he can't ) is something quite special:
"At the impossibly swank launch in Muscat of Amouage’s two Jubilation scents, guests found, upon arrival in their hotel room, a limited-edition bottle in a plain white box labeled simply Attar, i.e. fragrance. When sampled, this anonymous thing turned out to be breathtakingly beautiful, at once lofty, tremendously radiant, and dizzyingly rich. Faced with such an apparition, most of us immediately look around for someone to share our impressions, and the more witnesses the better. I felt the usual mixture of pride and frustration at being in possession of a thing of beauty that few others could share. For company, I gave some to my eight-year old daughter who wears it on big occasions.
Thankfully, this mysterious Attar, renamed Homage, is now available in limited distribution. The firm tells me it was composed in house, chiefly of Cambodian oud, Taif rose and Omani silver frankincense, which is to say, the best and most expensive stuff around. Oman was making perfumes when Europeans only bathed once a year on doctor’s orders. While there, I had occasion to sample, both in shops and in the wake of passing Omanis, the local style of oud, a fiercely elegant accord of rose and wood that radiates aquiline beauty. For Homage, the firm has gone one better on the usual composition and added not only frankincense, which fills the composition with stratospheric light and ice, but apparently some citrus oils to make it more pleasing to Western noses. Mine finds it irresistible."

If "in-house" means this was not made by Duchaufour that would be a good sign (i.e. it might actually smell like a genuine Arabian perfume and not another Iso E Super and fruit loop floral blend a la Jubilation XXV or Paestum Rose - which can be nice every once in a while but sure ain't worth the cash you have to fork over, for an Amouage at least)
I would personally recommend trying to find a bottle of vintage (!!!) Czech&Speake No. 88. Though I would not know where to start looking.
