What's the question here? Is it about which turns in F1 tracks are more risky than others, which ones are the biggest challenges to get right, which turns are most exciting or which are the scariest or simply the most fun? Or is it about the best being the ones that combine all of that? As ever it's subjective and hacking through the tightly confined streets of Monaco at a ton is probably as scary and life threatening as doing twice that on a circuit with lots of run-off.
Like most of the great corners of the past Eau Rouge and 130R have now both been neutered by the creation of their large run-off areas. Nevertheless they are no doubt still two cracking good challenges and fun for the drivers. IMHO, pulling off a clean pass on a close competitor on either turn is an exhibition of opportunism, guile, skill and bravery, period.
