Decorator's Assistant is a safe bet.
Namely, because it only works on items that you can pick up.
Redecoration allows you to move anything.
Houses, trees, great big sections of wall, you name it.
Needless to say, that means you have to be super careful when you decide to re-arrange your house.
In fact, what you could do is download both, and only use Redecorate if you plan on moving some furniture. Otherwise, DA should work just fine.
