I do use a S23U and I surprisingly did like the default PenUP drawing app and how there's audio feedback that gives an additional feeling of texture to the drawing for that and Samsung Notes. S23U seems to make better use of the Spen than iPad does with the Apple Pencil. I use the smart select option all the time to do things like extract text. And wish iPad had an equivalent of one hand operation+ and edge panel.
I don't know I would change to a Samsung tablet though. Not because I greatly prefer the apps or OS on iPad, but because I feel more confident in long term support from them. If custom roms were around for Android tablets that had a spen quality stylus I'd switch in an instant knowing that when support stops I can move onto custom roms to use even longer. But until then I've been prioritizing updates for what is essentially a dedicated comic reader a majority of the time.
