Of the Rollei R3, RLC and RHS developers, none of these show the generic attributes of D76 nor ID11.
The RLC seems identical the former Labor-Partner Docufine (extremely fine grain) developer in being as expensive and fine grained, however offering little advantage over Ilford Perceptol. It may be beneficial for you since it has a higher operating temperature for development. Otherwise, I think I would use it more, being an ideal film developer for landscape work. Labor-Partner used to supply Docufine in 1 litre brown stock bottles; the RLC seems to offer a third of the molar concentration for the same volume at a hugely challenging price point, and its smaller sizes seems to suggest that it is targeting the 35mm format market directly. It is an effective developer for high contrast film like Maco Ort. Technical Pan and Rollei IR400 too.
Similarly, the Rollei R3 shows much in common with Ilford Perceptol (metol), being an ideal developer for R3 film and IR400 at ISO25 and ISO3 respectively, however working out more costly than Ilford Perceptol and operates better as a depth developer. It is available in larger bottles and is offers fine grain and contrast control than either ID11 or D76.
The RHS (High Speed) developer is quite exceptional, both in terms of its cost and its small vial size, barely offering enough to develop a handful of sheets. However it is the favoured combination for developing Rollei R3 film at ISO 3200 - 6400 perhaps the only recently available sheet film capable of being push-processed for LF nocturnal hand-held work. It has far superior push-processing control than D76 or ID11, and rivals Ilford Microphen in that respect (when tested with Rollei R3 film).
All of the Rollei developers have the advantages of direct dilution from the liquid stock. In answer to your question - the Rollei developers are a confusing blend of both relabelled/marketed developers, in addition to newer formulations for specific Rollei branded and associated brand film products. They will probably not offer the generic ease of ID11 or D76, however have superior characteristics for set film combinations for more specialist application.
Kind regards,
