So more gimmicky fluff,
I find Generative Remove incredibly useful. I'm not looking to create fantastical photographs: I'm working on a series, photographing historical buildings in my city. Being able to easily retouch out parking signs and other small visual distractions is really wonderful.
However, as with many functions in Lightroom where you're moving/replacing pixels, the implementation in Lightroom is hobbled/awkward compared to the implementation of the same function in Photoshop. I've always found the clone/healing tools in Lightroom to be painful to use compared to Photoshop but the ability to stay in RAW in LR is sometimes worth it.
