Received my S24U 512gb today too, earlier than expected (quoted 26th). I managed to get in on the £910 code stacking with the free case/protectors and watch. So a pretty good deal.
Phone seems decent enough, although it's amazing how well a Note 10+ 5g holds up in comparison. I've not messed with the camera much yet, but except for refresh rate the screen and general feel are really similar.
I went for the Spigen cases and tempered glass protectors which are coming tomorrow. The Spigen tempered glass ones have been really good for iPhone, so I'm glad you can get them on Samsung now too with the flatter screen.
