Imperial case wax is old school and a personal favorite
I would say that for spray lubes I preferred Dillon over one shot
The fact is I have a 550B and several single stage presses, I prefer to load 1 at a time single as it is QC at it's utmost.
I am happy to load this way as I enjoy the time spent loading almost and sometimes more that the shooting
Imperial should be on everyones bench, I also use it as a ram lube, die protectantand on occasion a slight amount on bolt of hunting rifle
