We have the Elegant Grand Fir 9’ in the foyer and I love the shape and width. It’s not a slim tree but it’s more compact. It does not have colored lights and its white lights are warmer than the Grand Duchess. 
We have the Grand Duchess SLIM 7.5’ in the office and the lights are a bit brighter and cooler. It’s sooooo easy to install with minimal fluffing. It does have colored lights option and my kids love that. Which is my favorite? Both lol. I love the fullness of the Grand Duchess in the right space but went with slim for a small corner. I also Leo the height and sparse top of the Elegant Fir. I believe both work perfectly depending on what you need. I’d skip the Jackson Noble, it’s tough to fluff and I don’t love the base!
