A RC hole hammers the rock at the end of the drill hole into small chips and fines.
A diamond hole produces a solid core of rock, usually in lengths of about a metre. The core is usually cut lengthwise into halves and quarters before assay. One section is assays whilst the rest is retained some of for future reference.
Each has different methods of sample preparation prior to analysis.
Each will be logged by a geologist, identifying minerals/oxidation anything of geological interest.
The core provides more information as it is spatially intact.
That is a very simple explanation.
The assay methods are the same.
The diamond holes might take a little longer than the RC due to the core cutting.
That's my take.
