I have heard of platinum being rhodium plated before on rare occasions, but I would assume it is not. But there's not a thing wrong with asking! White gold is plated because it is yellowish. Platinum is already white (silver, actually), so there is no need to plate.
Matter of taste, really - I much prefer platinum because I like the heft of it, I like the way it displaces from a scratch so that it can be polished back to its original condition, and I like how the ductility makes for safer prongs.
Concerning rhodium: it's basically a cheap and non-labor intensive way to make metal look shinier. The plating won't rub off more quickly, but it's a micron thick, so as the metal underneath it wears, so, too, does it - which means the shine won't last forever. Honestly, I'd just ask the jeweler: I prefer mine unplated, too, because I like the look of greyish look of platinum more than the whiteness of rhodium.
