"best you can afford" has the same protection as "the cheapest you can buy".
anything to back that up? Interesting sweeping generalisation. Yes, the more money you spend you tend to get more vents, better strap/retention systems etc, but I reckon you're stretching a point there.
A generalisation, but they all pass the same tests, so as far as protection goes, it holds, and I've not seen anything to counter it.
Every single helmet I've broken (6 total, 4 in crashes I think) has cracked rather than crushed, so it seems they cracked before crushing, so in theory even a split helmet can provide some protection. Given the main protection is from cuts and bruises I don't replace every time it cracks.
