Hi Lafayette, and welcome.
I've been on the Freedom of the Seas, but not the Allure, so I can't really compare the two. However, if you do decide to go with the Freedom, I think you'll definitely enjoy it. As stated, in most cases, unless you have really choppy seas, you won't notice you're at sea.
If you want to look at it, my review of the Freedom of the Seas is posted here
