Samsung Galaxy note 4 or my current asus rog phone 6d. Note 4 was a peak of smartphone design, large screen, exchangable battery, stylus ( mostly for fun, i do like to have phones that have something special in them, but it was quite usefull for playing nonograms , havent actually used it for notes ever ) microsd, jack. Evrything ever needed in a phone was there.
Rog phone 6d on the other hand has suprisingly many features minijack ,TWO usbc ports , actually large storage ( microsd is good but android has a lot of limitations on what you can use it for so its not that usefull and you still need fairly large internal memory unfortunetly ) and most imporantly the back has rgb ( have i mentioned that i like phones that have something special ). Also it comes with a fast charger included ( which shouldnt be special for such an expensive phone but apparently getting single usb cable for charging somehow became a standard practice ). Also a large screen and it looks sick.
Im suprisingly on board for ai art. It does allow you to create whatewer you want without having the technical ability to do so. ( For example of you want a sick wallpaper ) Ot significantly lowers the floor as far as creating anything art related goes.
