Rust is more zoomer attention span friendly fast paced but after hitting stones for 12 hours and building your base you'll have some Russian kid blow it up at night and lose everything.
DayZ is mostly walking and walking and more walking but has more engaging survival aspects. You will get shot from a bush after walking for 12 hours without seeing a living soul and lose everything.
In general Rust will be more fun on average but DayZ will be boring for most of the time but the rare times shit happens you'll get insane adrenaline injections.
