If your goal is to put pubkeys in order, PR and GR can both serve that purpose in a meaningful way. May as well do the one that is easier to calculate.

If your goal is to do anything that requires a pubkey-specific WEIGHT, such as tallying votes or doing a weighted average, GrapeRank is better than PageRank because PR is inherently a popularity contest, and most of us don’t want weight to be proportional to popularity. Most of us want weights to be proportional to merit or quality, in the relevant context.

GrapeRank is inherently designed to create contextual scores. One context might be designed to distinguish real users from bots, ie a binary outcome (this is the GR score currently available on my site). Another context (I have not yet implemented on my site) might be designed to reflect a pubkey’s expertise in some topic on a scale from min to max. Either of these scores are suitable to be used as the pubkey’s weight in the relevant context.

It’s not clear to me how to do this with classical PageRank. Unless you modify it, of course.
