I'd also choose Operation Chariot straight away.
The St Nazaire Society (Operation Chariot)
Five VCs in a few hours is not exactly a common occurrence.

On the Axis side, Eben Emael immediately springs to mind (if it counts as 'a raid'? ). Witzig's boys certainly went into a very specifically defined target and achieved dramatic success against far superior numbers & strong defences.
Airborne Operations of Sturmabteilung Koch 10

Operations NIWI & Hedderich, as cropped up in this thread also qualify as pretty unusual raiding behaviour, with their overloaded Storches and a somewhat radical approach to warfare.
