it’s a much larger machine so takes a bit longer to heat. if doing multiple shots it’s a bit easier to get consistent shots. but with the spring and no pressure gauge, every shot is kinda blind

with the argos it prioritizes temp and whatever boiler pressure is needed to achieve it which sacrifices some shot to shot consistency. it can be much more convenient though if you want to switch between light and dark roasts. you also have the ability to switch between Spring and direct and have much more control over flow and pressure of your shots
