Aircraft X checked onto departure and was instructed to 'Climb via SID'. The pilot then should climb via the SID up to FL200. This pilot was on the RDRNR3 Departure and leveled off at 100. There was confusion on the pilot's end citing clearance delivery stopped their climb to 100. Departure then instructed the pilot to 'Climb via SID top altitude FL200' and the pilot then understood to continue their climb. This is an instance of pilot confusion that repeats itself every day at ABQ TRACON. Aircraft on clearance should be instructed to 'Climb via SID' with no altitude restrictions; and if Approach needs an altitude restriction this will be given upon aircraft check in. -OR- All pilots need to be on the same page that when Departure clears an aircraft to 'Climb via SID' this deletes the clearance delivery restriction previously given.
Reporter stated that they would like the climb via phraseology fixed; it has been going on for about 5 years and still causes problems.
ABQ TRACON Controller reported pilot confusion relating to a 'Climb via SID; with an altitude to maintain that was not the top altitude.
