Same tradeoff as all gear really.
The MX collar was a good compromise, allowed enough head movement to still do head checks.
I stopped wearing it when I got a new jacket and it wouldn't fit properly.
No idea on how effective it would have been in a crash, but reducing general wear and tear on an ageing neck it was brilliant.
