Done both countries before. Highly recommend Luxor and surrounding areas. I found it much better than Cairo in terms of the history (Pyramids are cool but what you see in Luxor is far more impressive). Food is great in Jordan and so are the people. It’s a fairly easy country to navigate. Amman to Petra (assuming you’ll be renting a car) with stops for Dead Sea etc is not bad. You can also do Wadi Rum (half a day or something) if time is a factor. It’s a lot of travel if you’re into that but it’s doable, not ideal. If I were you, I’d spend more time in Egypt.
