The diode is easier but not as strong as the K40 which equates to much slower. One thing the diode has going for it is a larger work area. The K40 is 12x8 (although I did get a little more out of it by removing the table from it. But I ended up putting in a powered Z table in it so I'm back to 12x8. The diode I have (Ortur Aufero) is 390mm x 390mm. They have an extension kit for it to take it to around 600 x 390.

For either a diode or CO2, an air assist is a must! I tried one of those 45L/m aquarium style pumps on both the diode and K40, it almost works ok, keeps the fire blown out (usually) but have since gone to shop air, a local water separator and a good regulator.

Lastly, if you can, vent outside. I have a 230 CFM inline exhaust and it's not quite enough so I'll be changing that out real soon. I have that going to a dryer vent.
