The advantage of a tank is that it will inflate the tires really fast.
The disadvantage is that you have to recharge them, valves may leak, large in size.
( I'm not counting that it doesn't need batt voltage to operate since if you don't have 12v source, you have bigger problems then topping off tire pressure).
The advantage of a good compressor is that it is always with you and ready to work. Small in size in comparison to a C02 tank. Most if not all do not require maintenance.
Disadvantage is that they take longer to inflate and make noise.
I have a cheep $60 compressor for last 3 years and it does the job. It does take about 5 min per 35" tire to bring pressure from 18 psi to 35 psi but then again it is cheep compressor. It is time for me to upgrade and I was considering CO2 tank but will be going with a compressor. ARB is very expensive but the twin motor unit will inflate a 35" tire from 0-35 psi in a minute. I am probably will be going with Puma unit and separating the tank from compressor assembly.
