For a good paper on this topic, I have to recommend Werfel et al. 2017:
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0173677
They make a spatial model of a world where resources replenish at a fixed rate and show that mortal populations outcompete immortal populations by improving their children’s fitness, as there are fewer mass starvation events.
