I own both Daim Blond and Magnetism and love them both ... both would be in my current top 10.
Magnetism I've worn more than any fragrance recently since it camo out. I wear it everywhere ... to work, dinner, etc. It's a very versatile scent and I can't explain ... I just like it.
Daim Blond is another excellent one in my wardrobe, but not as versatile. Very much of a suede scent and , although better suited for a night out, I do wear it to work once in a while. I paid plenty for it but worth every penny.
I don't think you can compare one to the other. Magnetism is a "grapey" kind of scent as opposed to a very soft suede scent of Daim Blond. In my book, you can't go wrong with either ... but as always ... sample Daim Blond first at that price.
