honestly i think canned is still the best for its practicalliy i say that because its not bad, the pressure is perfect it small gets inbetween somethings a air compressor cant when you turn the pressure down, its only like 5-7$ usd last long enough to make 2-3 good cleans and about 20 touchupslooks good too to have it on your desk to show you care, and you dont have to lug your case out of your room or whereever and just vacuum the dust off your carpet later. theyre decent little nifty tools IMO
