If you think about it , most of the force involved is almost all straight through the rod into the crank . Compression is upward against mounting pressure and then the big boom driving things back down . All that action is , for the most part , exerting pressures right though the rod into the crank . A downward pressure . So , 'other' pressures are much less . The rod ends are round to basically keep the pins and rod in alignment and as a byproduct keeps things together .
Anyway , like I said , you'll be pushing , so go with the bushing .
I'd make sure that that bushing gets enough lube while it's doing it's job .
