I was training a CPC-IT (In-Training) on South Departure and we were discussing when to use the climb via and when it would be best not to. There were arrivals into IAH that made it a good opportunity to use the climb via clearance with Aircraft X. Aircraft X checked in climbing via the FLYZA1 departure. The CPC-IT issued Aircraft X Climb via the FLYZA1 Departure except maintain 16;000. The pilot read it back correctly. I told the CPC-IT that even though we issue the climb via clearance we still need to make sure they comply with the altitudes. I saw Aircraft X climbing out of 3;400 at a normal rate. Then a supervisor was walking behind me and asked for a PIREP and I turned my head and gave him the PIREP from the previous aircraft. I turned my head back to the scope and saw Aircraft X climbing through 6;800 right in front of Aircraft Y who was on the HCKRY1 arrival turning the downwind at 6;000. I keyed up the microphone and told Aircraft X the top altitude was 5;000 at BOTLL intersection and a possible pilot deviation. Aircraft X did climb a lot faster than all the previous departures; they climbed 4;000 in 3 nm.Somehow change the phraseology so that pilots understand to comply with the altitude restrictions on the departures.
I90 controller reports of issuing a climb via clearance; the pilot reads it back correctly; but the aircraft misses a crossing restriction which leads to a loss of separation.
