I'll probably get flamed for saying this but IMHO the Chippy and RV are incomparable. The Chippy is iconic and oozing nostalgia whereas the RV breed is Meccano like kit build.
I think that's absolutely right. As well as (Pace) being possibly the best handling SEP (OK, I haven't flown an RV) what the Chippy has in spades is character! It looks like a Spitfire. When you strap it on (you don't 'get into' a Chippy) one slides down into the seat just as one sees Spitfire pilots do - both hands on the windscreen arch top; it just feels so natural. Even when taxying it vibrates, it rattles, it pops, it blatters, it's 'alive!'.
