Floating vs Glue - floating is cheaper and easier to install no doubt. You also save on floor prep - just clean off the big lumps and if so inclined vacuum the floor. Then lay down the padding and start the wood. There are engineered wood products that have a click/lock T&G system - like many laminate products. Super fast and easy install.

HOWEVER - and this is strictly a matter of personal taste - you have to walk on the floor. I have always hated a floating wood floor. I hate the way they feel under my feet and hate the way they sound when walking on them. To the casual observer they will appear to be a laminate product. Bottom line they feel cheap - YMMV.

Go to a flooring center that has all of these products installed for you to experience. Honestly weigh out the pros and cons of the product and costs. The wife and I agonized for months over our choice of wood (colors, wood type, style, cost) before making our decision. You can bring store samples home to compare. One thing we didn't agonize over was the installation method - glue down all the way.
