Just returned from a 7-night western caribbean run onboard Oasis of the Seas. It was a great trip on a wonderful ship. Now having sailed both Oasis and Allure, I'd say they were able to "tweak" Allure with a few improvements over Oasis that given Allure my vote for better ship. A few things that I really enjoyed about Allure that Oasis did not have: iPod docking stations & clocks in every cabin, Dog House (hot dog place and Rita's Cantina. Pretty minor stuff, otherwise the ships are almost identical. The shows onboard both ships were amazing, the cruise line really did a wonderful job with the production aspects.
From a port of call perspective, the only new stop for me was Falmouth, Jamaica. The port area they built for the ship is really nice, or should I say will be really nice when they complete it. It's going to have some really nice shopping areas, food places and stores. Right now, it's still under construction. I'd probably give it a year before it's fully operational. I was a bit surprised that it's a full (1) hour drive from Falmouth to Duns River Falls. For some reason I did not expect the distance to be that great; if you're doing the falls - it will turn into a full-day activity for yourself. We took a cab, it cost us $35 per person round trip. Then there is the $15 fee to enter the park. As such, if you're looking to do the tour "on your own" - plan to spend at least $50. In comparison to Ocho Rios, where the cab will only cost you like $10.
We dined at Chops, Giovanni's Table, Zumi and Solarium Bistro. All were very good, no complaints.
I have been on both myself and found them about the same. I did like the Doghouse on the Allure. I will be back on the Oasis in april 2012.

Well, they both do the same itinerary depending on which week you want to go (they both akternate between east and west caribbean). I think Oasis is a nicer looking ship - but Allure is a more complete ship. Allure already has Samba's grill, Ritas cantina, Dreamworks, etc. Oasis may have all of those things by the time you book - or maybe not.Either way, you will enjoy it.
