I know he is pretty untouchable on here, but i would take Vuna over Jimmy any day. Both have different strengths but despite the endless Jimmy love this season he hasn't been anything special. He started the year well but done nothing of note since a few rounds in. Our left side is our worst defensive side and he has been making errors too, not just the men inside him.... quite uncharacteristic. He has a few line breaks but i'm not sure he has any that Tahu hasn't gifted him (his centre is right up there for linebreak assists in the NRL). Jimmy was poor last season for the most part as well.
I am not suggesting he has been bad necessarily, but nothing special, and he is IMO greatly overrated around this joint. He deserves to stay here and keep his spot (i don't regard him a problem here by any means), but he is replaceable and he isn't in the same class as Vuna.
